The QPA2237 from Qorvo is a GaN power amplifier that operates from 0.3 to 2.5 GHz. It provides saturated power (Psat) of 27 dBm, PAE of more than 48 % with a small signal gain of 18.5 dB. The amplifier requires a 32 V power supply and draws 360 mA of current. DC blocks are required on both RF ports and the drain voltage must be injected through an off chip bias-tee on the RF output port. It is available in a low-cost, surface-mount, 20 lead, OVM QFN package that measures 4.0 x 4.0 x 0.85 mm. This amplifier is ideally suited to support both radar and communication applications across defense and commercial markets as well as electronic warfare.
