ATR0610-EK1 - GPS 1575.42MHz LNA Evaluation Board | Microchip
The Microchip Technology ATR0610-EK1 is an evaluation board for the ATR0610, a 2.7V GPS low noise amplifier (LNA) operating at 1575.42 MHz (GPS L1 band). The board is supplied with the demo board itself and is designed to demonstrate the performance of the ANTARIS4 GPS front-end LNA solution. A GPS low noise amplifier is a radio-frequency (RF) component placed directly after the passive GPS antenna in a GNSS receiver signal chain. Its role in the receiver hierarchy (antenna -> LNA -> SAW filter -> GPS RF front-end -> baseband) is to amplify the extremely weak satellite signals - roughly -130 dBm at the antenna - while adding as little noise as possible, because the noise figure of the first amplifier stage dominates the total cascade noise figure of the entire receiver. Key characteristics of the evaluation platform include operation at the 1575.42 MHz GPS L1 frequency, a nominal 2.7 V supply rail for the LNA, and demonstration of the ATR0610 gain and noise performance defined in the manufacturer datasheet. The board allows engineers to quickly connect an active or passive GPS antenna, apply supply, and verify signal acquisition behavior with an ANTARIS4 GPS receiver before committing to a custom PCB layout. Technically, the ATR0610 LNA is optimized for battery-powered portable GNSS devices: the low 2.7 V operating voltage aligns with single-cell Li-ion and 3.0 V coin-cell derived rails, and the device provides the gain required to overcome downstream filter and trace losses. The evaluation board exposes the RF input and output through standard coaxial or antenna connectors so that noise figure, gain, and current consumption can be measured with standard RF test equipment. Typical applications for the ATR0610-EK1 include GPS handheld receivers, automotive navigation modules, asset-tracking trackers, and any portable GNSS design where antenna-to-receiver link budget is critical. It is also useful as a reference for antenna matching network design at 1575.42 MHz. Design consideration: when evaluating, keep the LNA as close to the antenna as possible in the final design, since every dB of loss before the LNA degrades system noise figure one-for-one; the 2.7 V supply should be well decoupled to avoid supply-borne spurs. This page adds value beyond the manufacturer datasheet by consolidating distributor sourcing links, evaluation-board usage guidance, and drop-in-replacement analysis in one place.

Typical applications include vehicle tracking and fleet management, shared mobility (e-scooter, e-bike, ride-share), asset tracking, precision agriculture, and ADAS platforms. The module's RTK capability makes it well-suited for drones, autonomous robotics, and surveying equipment requiring centimeter-level accuracy. When designing with the LC29D, ensure the host processor can provide RTCM correction data over UART or IP connection for full RTK operation. Route the RF input trace with controlled impedance and place the antenna as far from noise-generating circuitry as possible to maximize CN0. Use the recommended L1+L5 stacked patch or active multi-band antenna.

The LC79D module at the heart of the kit is a multi-constellation GNSS receiver module that integrates a 28nm GNSS chipset, on-board LNAs and SAW filters, and an advanced low-power management solution. A GNSS receiver module is a satellite-radio receiver that calculates its own 3-D position, velocity and time by trilaterating ranging signals from multiple Medium Earth Orbit (MEO) and Geosynchronous (GEO) satellites; in the broader taxonomy, GNSS modules sit under satellite-positioning receivers, then radio-frequency receivers, then wireless modules, then electronic modules. Quectel's LC79D family targets fleet telematics, vehicle tracking, asset monitoring and AIS-140-compliant in-vehicle systems. Key features of the development kit include direct access to UART, I2C and PPS interfaces, integrated SMA connector for active GNSS antenna, USB-to-UART bridge for direct PC connection, status LEDs for power and 1PPS, and a regulated 3.3V reference supply. The on-module LNAs and SAW filters harden acquisition against weak-signal and jamming-rich environments, which is critical for aftermarket vehicle installations and metal-shielded telematics enclosures. The LC79D module uses 28nm CMOS process technology, enabling the low power consumption that battery-powered asset trackers require. Multi-constellation concurrent operation shortens time-to-first-fix (TTFF) and improves position accuracy in urban canyons, where single-constellation receivers suffer frequent dropouts. The module is AIS-140 compliant, an Indian automotive telematics standard that mandates specific update rates, accuracy and security features for commercial vehicles. Typical applications include AIS-140-compliant vehicle tracking units, fleet management telematics, e-call and ERA-GLONASS-style emergency call systems, two-wheeler telematics boxes, asset tracking and cold-chain monitoring, and shared-mobility scooter trackers. The evaluation kit accelerates bench validation before committing to a custom LC79D carrier PCB layout. When designing with this kit, always use the included active LNA antenna in the SMA port for first-time verification; passive antennas will yield degraded CN0 figures and longer TTFF. Ensure host firmware drives the LC79D's on/off and reset pins per the LC79D GNSS specification rather than relying solely on supply-rail cycling, since the module's backup-domain logic requires a controlled shutdown sequence to preserve ephemeris.

A built-in LNA removes the need for an external low-noise amplifier, and reception works down to -165 dBm without an assistance network. EASYTM self-generated orbit prediction (Embedded Assist System) combined with AlwaysLocateTM technology dramatically reduces TTFF in cold-start and periodic-wakeup scenarios. PPS output support enables precision time applications. Technically, SIM68M supports autonomous GPS/GLONASS/QZSS/SBAS (WAAS, EGNOS, MSAS, GAGAN) operation and simultaneous multi-constellation tracking of mixed satellite signals on the 1575-1616 MHz L1 bands. The SMT LCC package with castellated edges suits standard reflow assembly and automated optical inspection, and the antenna is connected through an RF pad on the module edge. Typical applications include vehicle and asset trackers, fleet management telematics, drone and UAV navigation, and IoT location beacons, where low power, fast TTFF and multi-constellation robustness in urban canyons matter most. Design consideration: supply the module from a clean 2.8 V to 4.3 V rail (typ. 3.3 V), keep a 1 ppm-class TCXO-equipped passive antenna within 1-2 m of the module, and reserve PCB area for the 18-pad footprint so the pin-compatible SIM68ML variant can be adopted later.

It delivers centimeter-level RTK positioning and precise attitude (heading) information by simultaneously exploiting all major GNSS constellations, including GPS, GLONASS, BeiDou, Galileo, QZSS, and NAVIC. An all-band GNSS receiver is a positioning radio that simultaneously tracks the L1, L2, L5, L6 and similar carrier frequencies broadcast by every major satellite navigation system. Compared with single-band (L1-only) modules, an all-band receiver resolves the ionospheric delay error that otherwise limits horizontal accuracy to roughly one to three meters, enabling real-time kinematic (RTK) fixes at centimeter precision. The ZED-X20D belongs to u-blox's professional-grade X20 platform, targeting OEM integrators of robotics, autonomous vehicles, precision-agriculture machinery, and other industrial systems that demand sub-degree heading plus RTK position from two antennas on a single moving platform.

The 54-pin LGA footprint is pin-compatible with the higher-tier ZED-X20P, allowing designers to scale between heading and dual-frequency positioning variants without board rework. Architecturally, the ZED-X20D integrates an RF front-end, a multi-band GNSS baseband, a 32-bit application processor running u-blox's positioning firmware, and hardware accelerators for RTK and PPP convergence. The use of a dedicated heading engine reduces the time-to-first-fix for attitude and lets the firmware output yaw, pitch, and roll on a separate message stream alongside the position fix, with a heading update rate up to 10 Hz in the default firmware. Typical applications include precision-agriculture tractor and implement guidance, unmanned autonomous vehicles (UAVs and ground robots), construction and mining machine control, harbor and rail asset tracking, and surveying equipment. For drones and rovers, the headline benefit is robust heading even at zero velocity, which eliminates magnetometer drift on small platforms and short antenna baselines down to 50 cm. When designing with this part, allocate a 22×17 mm keep-out area on the top layer for the LGA and route the two antenna feeds (ANT1, ANT2) as short 50-ohm controlled-impedance traces, keeping both SAW filters and LNA close to the module pins to preserve phase coherence needed for accurate heading.

The Super-E mode delivers approximately 2.5x lower power than full-power operation while maintaining good positioning and speed accuracy. Technically, the ZOE-M8B is built on u-blox's M8 positioning engine with 72-channel architecture, ROM firmware, and a built-in TCXO for fast satellite acquisition. Communication is via UART, I2C, or SPI digital interfaces. The integrated dual-frequency RF front-end allows either GLONASS or BeiDou to be processed concurrently with GPS and Galileo, enabling simultaneous reception of three GNSS systems for faster, more accurate fixes. Typical applications include wearable fitness trackers, asset trackers, smart watches, IoT sensor nodes, and portable navigation devices where battery life and compact PCB area are critical. The 4.5 x 4.5 mm footprint and 12 mW Super-E power also suit disposable or energy-harvesting designs. Designers should note the ZOE-M8B is an older-generation product; u-blox recommends the MIA-M10 series for new designs. When migrating from ZOE-M8G, verify the minor differences in the SIM report (UBX-17045131) to ensure compatibility. Provide a clean 1.8V supply rail and follow u-blox's reference layout to maintain RF performance.
