MW7IC915NT1 概述
An RF power amplifier (PA) is the final active stage in a wireless transmitter that boosts a low-level modulated RF signal to the high power level required to drive an antenna. Within the transmitter signal chain, the PA sits between the transceiver/upconverter and the duplexer/filter, and it is the dominant contributor to DC power consumption at the base station. RF LDMOS (Laterally Diffused Metal-Oxide Semiconductor) technology, on a high-resistivity silicon substrate, has been the industry workhorse for sub-3 GHz cellular base station PAs since the 1990s because of its high power density, excellent gain linearity, and cost-effective volume manufacturing. The MW7IC915N family belongs to this lineage as a multi-stage integrated PA module rather than a discrete transistor.
Key features include 38 dB typical gain, 1.6 W average output power for W-CDMA at 28 V, multi-stage on-chip matching that eliminates external RF tuning, integrated bias networks for simplified gate biasing, and an operating supply range of 26 V to 32 V. The 24-PQFN over-molded plastic package provides a low thermal-resistance path and is compatible with automated surface-mount assembly, reducing both board space and manufacturing cost versus ceramic flanged packages.
Typical applications include 700/800/900 MHz cellular base station power amplifiers, W-CDMA and LTE driver/final stages, repeaters and small-cell infrastructure, and industrial/scientific/medical (ISM) band transmitters that share the 902-928 MHz range. The wideband on-chip matching makes a single SKU usable across multiple regional cellular bands.
When designing with this part, follow the manufacturer's recommended PCB layout exactly: keep RF input/output traces 50 ohm controlled-impedance, place the device on a board with sufficient copper thermal mass, and decouple the drain supply with the value and type of bypass capacitor specified in the reference design. The on-chip matching assumes the standard evaluation board stack-up; deviation degrades gain, efficiency, and stability.

典型应用
MW7IC915NT1 适用于 6 应用s: W-CDMA 900 MHz Base Station Driver/Final PA, LTE Band 8 / 900 MHz Small Cell PA, 700/800 MHz Public Safety Repeater, 902-928 MHz ISM Band Transmitter, Multi-Band Cellular Repeater / Booster, W-CDMA / LTE Driver Stage.
W-CDMA 900 MHz Base Station Driver/Final PA
The MW7IC915NT1 delivers 1.6 W average W-CDMA power at 28 V with 38 dB gain across 728-960 MHz, making it ideal as a driver or low-power final stage in 900 MHz W-CDMA picocell and micro-cell base stations. Its on-chip input and inter-stage matching eliminates the external RF tuning that discrete LDMOS transistors require, simplifying the cellular BTS RF front-end. Per the NXP datasheet, the two-stage LDMOS architecture maintains linearity across multi-carrier W-CDMA signals while the 24-PQFN package provides low thermal resistance for continuous downlink duty cycles.
推荐
LTE Band 8 / 900 MHz Small Cell PA
The MW7IC915NT1's 728-960 MHz bandwidth covers LTE Band 8 (880-915 MHz uplink, 925-960 MHz downlink) without retuning, supporting small-cell and enterprise femtocell deployments. The 1.6 W average output and high 38 dB gain reduce the bill of materials by removing an upstream driver stage, while the 24-PQFN 8x8 mm package fits inside compact small-cell enclosures. According to the NXP MW7IC915N datasheet, the integrated matching preserves gain flatness across the LTE Band 8 duplex spacing for consistent EVM and ACLR performance.
推荐
700/800 MHz Public Safety Repeater
The MW7IC915NT1 covers 728-960 MHz, which includes the 700 MHz and 800 MHz public-safety Land Mobile Radio (LMR) bands used by first-responder networks. Its two-stage integrated LDMOS design and 38 dB gain allow repeater designers to drive the PA directly from a transceiver/demodulator output, while the 1.6 W average rating provides the headroom needed for in-building coverage boosters. The 24-PQFN over-molded plastic package survives the higher ambient temperatures found in head-end equipment closets per the NXP datasheet thermal recommendations.
推荐
902-928 MHz ISM Band Transmitter
The MW7IC915NT1's broadband on-chip matching extends down to 698 MHz and up to 960 MHz, fully covering the 902-928 MHz unlicensed ISM band used by industrial telemetry, RFID, and short-range data links. Engineers can run the part at 28 V to deliver 1.6 W average CW or narrowband power for long-range ISM links, while the two-stage integrated design saves PCB area versus a discrete driver + final LDMOS pair. Refer to the NXP datasheet for ISM-specific bias recommendations, since the cellular-optimized default bias may not yield best efficiency on constant-envelope waveforms.
推荐
Multi-Band Cellular Repeater / Booster
Repeaters and signal boosters must amplify multiple downlink bands with a single PA chain to keep BOM cost low. The MW7IC915NT1's 698-960 MHz coverage with no external matching changes makes it suitable as a wideband final stage covering 700, 800, and 900 MHz bands simultaneously, subject to intermodulation trade-offs. The 38 dB gain simplifies the AGC loop, and the 24-PQFN plastic package is rugged enough for outdoor NEMA enclosures when paired with a proper heatsink per the NXP MW7IC915N datasheet layout guide.
推荐
W-CDMA / LTE Driver Stage
Higher-power base station PAs require a dedicated driver stage, and the MW7IC915NT1's 1.6 W average and 38 dB gain make it well suited to drive a 25-60 W NXP Airfast or Wolfspeed GaN final device. Its two-stage integrated design reduces the driver PCB footprint compared to a discrete LDMOS driver + matching network, while the 28 V supply matches the bias rail of typical macro-cell finals. The NXP datasheet application circuit shows the MW7IC915N family used as a driver for the AFT27S010N or similar Airfast transistors.

关键差异点
- Fully integrated two-stage LDMOS PA with on-chip matching （对比 Discrete LDMOS driver + final transistor pair)
- Single SKU covers 698-960 MHz without retuning （对比 Narrowband PAs that require per-band matching network swaps)
- Over-molded plastic 24-PQFN package （对比 Ceramic flanged LDMOS packages)
设计说明
Estimated: at Pout=1.6 W, Pin~26 mW (38 dB gain), and PAE~25%, total DC dissipation is roughly 4.7 W. With the 24-PQFN 8x8 mm over-molded plastic package mounted on the manufacturer's reference PCB stack-up, the junction-to-ambient thermal resistance is typically well below 10 C/W when a continuous copper thermal pad is used. For continuous W-CDMA downlink at 100% duty, place the device on a board with at least 1 square inch of 2 oz copper connected to the package bottom pad, and verify junction temperature against the NXP MW7IC915N datasheet thermal derating curve.
Follow the NXP reference PCB layout exactly: 50 ohm controlled-impedance RF input and output lines, via-fenced ground stitching around the package, and the package bottom exposed pad soldered directly to a continuous ground plane for thermal and RF grounding. Place drain supply bypass capacitors as close as possible to the VDD pins, with a 100 pF / 10 nF / 1 uF / 10 uF parallel combination to suppress decoupling from DC to the operating band. Any deviation from the reference stack-up can detune the on-chip matching and degrade gain, efficiency, and stability margins.
Estimated: do not exceed the 32 V maximum drain supply rating even momentarily - the on-chip LDMOS devices have no internal over-voltage clamp. Do not operate the part without proper gate bias, as the device can draw excessive quiescent current and self-heat. Avoid routing digital or low-frequency signals under the RF input/output traces to prevent unintended coupling into the on-chip matching. Finally, confirm the live NXP lifecycle status before committing to a new design, since the MW7IC915N family is NRND and alternatives should be qualified in parallel.
合规信息
