The GRF5536 from Guerrilla RF is a Two-Stage InGaP HBT Power Amplifier that operates from 3.3 to 4.2 GHz. It delivers a linear output power of +23 dBm (up to 85°C) with a gain of 27 dB. This amplifier is designed to deliver excellent P1dB, ACLR, and IM3 performance and has exceptional native linearity for transmitter applications that do not employ digital pre-distortion correction schemes. It requires a DC supply of 5 V and consumes 195 mA of current. The amplifier has flexible biasing that provides latitude for linearity optimization and also has a digital shutdown feature. It is available in a QFN-16 package that measures 3 x 3 mm and is ideal for cellular boosters/repeaters, automotive compensators, picocells/femtocells, cellular DAS, customer premise equipment, and wireless infrastructure applications.
