SR1020AB-MD110-MP1 概述
Ultra Wideband impulse radio is a wireless communication technology that transmits data using nanosecond-scale pulses spread over several gigahertz of spectrum, rather than a narrowband modulated carrier. Within the radio hierarchy, the SR1020 sits as a physical-layer transceiver solution under short-range wireless standards (802.15.4 UWB), competing in the same application space as BLE, 802.15.4 Zigbee, and LoRa radios, but offering far lower energy per bit and very low latency.
Key differentiating specifications include deep sleep current of just 920 nA and shutdown current of 55 nA, enabling multi-year coin-cell operation under defined use conditions and even energy-harvesting configurations. The active power profile is exceptionally efficient for the 6-9 GHz band: 0.39 mA/Mbps in receive and 0.12 mA/Mbps in transmit at 3.3 V, which is an order of magnitude better energy-per-bit than typical narrowband radios at comparable throughput.
The SR1020 architecture aggressively duty-cycles the radio, waking only for short UWB bursts. This yields microsecond-scale synchronization and low-latency links suited to wireless gaming peripherals, true wireless audio, and industrial sensor networks. Data rates from low-kbps telemetry up to 6 Mbps allow a single radio platform to serve both monitoring and streaming use cases.
Typical applications include wireless gaming headsets and mice, true wireless earbuds with ultra-low latency, coin-cell IoT sensors, and energy-harvesting industrial nodes where battery replacement is impractical.
Design consideration: because UWB performance depends on antenna integration and host-board grounding, follow the SPARK Microsystems reference layout and use the trace connector footprint exactly as specified in the manufacturer datasheet to preserve RF performance and regulatory compliance.

典型应用
SR1020AB-MD110-MP1 适用于 6 应用s: Wireless Gaming Peripherals, True Wireless Audio, Coin-Cell IoT Sensors, Energy-Harvesting Wireless Nodes, Industrial Sensor Networks, Low-Latency Wireless Control Links.
Wireless Gaming Peripherals
The SR1020AB-MD110-MP1's microsecond-scale UWB burst latency and 6 Mbps throughput make it ideal for wireless gaming mice, keyboards, and controllers where every millisecond of click-to-photon delay matters. Unlike BLE or 2.4 GHz proprietary narrowband links that suffer interference-related latency spikes in esports venues, UWB impulse radio resists narrowband jamming across its 6-9.3 GHz spread spectrum. The 0.39 mA/Mbps RX efficiency at 3.3 V keeps peripheral battery weight low, and 920 nA deep sleep preserves charge between gaming sessions. The trace connector mount lets designers place the module at the optimal antenna position inside a mouse or controller shell.
推荐
True Wireless Audio
True wireless earbuds and headsets benefit from the SR1020's combination of 6 Mbps throughput and duty-cycled ultra-low energy: 0.12 mA/Mbps in TX at 3.3 V means a typical audio stream consumes a fraction of the energy a narrowband radio needs for the same payload. SPARK Microsystems targets this exact use case, since UWB's nanosecond pulses enable synchronization between left/right earpieces with sub-microsecond skew - critical for stereo imaging. The 55 nA shutdown current means the radio effectively disappears from the earbud's power budget when idle. The MD110 module's integrated antenna removes the hardest RF design step from miniaturized earbud enclosures.
推荐
Coin-Cell IoT Sensors
For IoT sensor nodes powered by CR2032 or LiSOCl2 cells, the SR1020AB-MD110-MP1's 920 nA deep sleep and 55 nA shutdown currents allow multi-year battery life under defined reporting intervals, per SPARK Microsystems use-condition data. A sensor waking once per minute for a short UWB burst spends nearly all its life in deep sleep, so battery capacity is consumed mainly by brief high-efficiency transmissions (0.12 mA/Mbps TX). The module's integrated antenna and trace connector mount simplify retrofitting wireless connectivity onto existing sensor PCBs without RF expertise, shortening certification and development cycles for industrial monitoring products.
推荐
Energy-Harvesting Wireless Nodes
The SR1020's aggressively duty-cycled architecture explicitly supports energy-harvesting configurations, according to SPARK Microsystems. Indoor photovoltaic, thermoelectric, or RF-scavenging sources deliver only microjoules per second, so every radio activity matters: shutdown at 55 nA and burst-mode efficiency of 0.12 mA/Mbps TX at 3.3 V allow a harvested-energy node to accumulate enough charge between transmissions to send sensor readings across the 6-9.3 GHz UWB band. The MD110 module form factor lets energy-harvesting reference designs integrate wireless without antenna layout risk, keeping the harvested-energy budget devoted to useful transmissions rather than leakage.
推荐
Industrial Sensor Networks
In factories, the SR1020AB-MD110-MP1 provides robust short-range links immune to the 2.4 GHz congestion caused by Wi-Fi, BLE, and Zigbee traffic, since it operates in the 6-9.3 GHz UWB band. Wideband impulse radio also penetrates multipath-rich metal environments with low latency, supporting closed-loop control and safety interlocks that narrowband radios handle poorly. With multi-year coin-cell capability, retrofitting vibration or temperature sensors onto rotating or mobile equipment requires no wiring. DigiKey stocks the module (ships today as of 2026-10-20), simplifying maintenance sourcing for deployed industrial fleets using the SR1000 platform.
推荐
Low-Latency Wireless Control Links
Robotics, drones, and professional AV control benefit from the SR1020's sub-microsecond synchronization and deterministic duty-cycled bursts. The 6 Mbps maximum rate carries control channels plus telemetry simultaneously, while 0.39 mA/Mbps RX keeps receiver nodes light enough for battery- or harvester-powered actuators. UWB's impulse nature gives predictable time-of-arrival, so control packets avoid the retry storms narrowband radios experience near Wi-Fi access points. The MD110 module's trace connector mount permits placement on carbon-fiber or metal chassis edges where antenna clearance is best, maintaining the 6-9.3 GHz link budget in demanding electromechanical assemblies.

设计说明
Replicate the trace connector footprint exactly as defined in the SPARK Microsystems SR1020 datasheet. Keep an uninterrupted ground plane beneath and around the module, and reserve a keep-out area around the integrated antenna region free of copper, traces, and enclosure dielectrics. Because UWB occupies 6-9.3 GHz, even short stub mismatches degrade the link budget; validate with the SR1020AB-EVK1P4-MP110 evaluation kit before freezing the host PCB.
Design the 3.3 V rail for burst loads: although average current is dominated by 920 nA deep sleep, transmit bursts draw current at the 0.12 mA/Mbps TX efficiency point. Use a low-quiescent-current LDO (Iq < 1 uA) or feed directly from a lithium primary cell with adequate headroom, and place bulk capacitance near the module so burst currents do not droop the rail and reset the radio during cold coin-cell conditions.
Do not treat the SR1020AB-4Q28-TR QFN IC as a module substitute: swapping requires a new antenna design, matching network, and regulatory re-testing. Also, do not estimate battery life from sleep current alone - actual lifetime depends on the duty-cycled TX/RX burst profile under your specific use conditions, as SPARK Microsystems states multi-year coin-cell life is defined only 'under defined use conditions'. Model your link schedule before committing to a cell size.
