Ku/K-Band GaN PA optimised for defence and commercial SATCOM

23-09-2022 | Mouser Electronics | Power

Mouser now stocks the QPA1724 Ku/K-Band GaN power amplifier (PA) from Qorvo. Delivering double the power of similar PAs and providing exceptional wideband linear power, gain and power added efficiency, the device is a market leader in RF performance for commercial and defence markets.

The device is a high-power MIMIC amplifier for the 17.3GHz to 21.2GHz SATCOM (Ku-K) band. It delivers a saturated output power of 20W (~43dBm) with a small signal gain of 25dB and PAE of 27%. Fabricated utilising Qorvo’s production 0.15μm GaN-on-SiC process (QGaN15), the device comprises on-chip blocking capacitors following the DC grounds on the input and output ports. The PA is also fully matched to 50-Ohms with DC grounded I/O ports for peak ESD performance to simplify system integration.

Ideal for commercial and defence radar and SATCOM applications, incorporating low-earth-orbit constellations and wide bandwidth, multi-carrier high-data throughput solutions, the device is offered in a 7.5mm × 6mm × 1.6mm QFN package and 100% DC and RF tested to provide compliance with electrical specifications. For evaluation and development, the QPA1724EVB evaluation board is available from Mouser.
