The GRF5606 from Guerrilla RF is a Two-Stage InGaP HBT Power Amplifier that operates from 663 to 716 MHz. It delivers an output P1dB of 3.6 W (~35.6 dBm) with a small signal gain of 27.5 dB. The amplifier exhibits exceptionally native linearity, making it ideal for transmitter applications that typically do not employ digital pre-distortion correction schemes. This power amplifier has a rugged design that offers resilience to mismatched loads. It requires a DC supply of 5 V, consumes 240 mA of current, and provides flexible biasing for linearity optimization. This RoHS-compliant amplifier is available in a 16-lead QFN package that measures 3 x 3 mm and is ideal for cellular boosters, automotive compensators, picocells/femtocells, and customer-premise equipment applications.
