The GRF5526 from Guerrilla RF is an RF Power Amplifier that operates from 2.5 to 2.7 GHz. It provides 30 dB of gain with a noise figure of 3.3 dB and a P1dB of 32.2 dBm. This two-stage InGaP HBT PA has exceptional native linearity, which makes it an ideal choice for transmitter applications that typically do not employ digital pre distortion correction schemes. This amplifier has been specifically designed for 5G wireless infrastructure applications requiring exceptional native linearity over large 100 MHz bandwidths and temperature extremes of -40°C to 85°C.
The amplifier can maintain ACLR levels of better than -45dBc, IMD3 levels < -20dBm, EVM levels < 1.5%, and PAE Efficiencies in the 14% range without the aid of supplemental linearization schemes like digital pre-distortion (DPD). It requires a DC supply of 5 V and draws 153 mA of current. This PA is available in a surface mount QFN-16 Package that measures 3 x 3 mm. It is ideal for cellular boosters/repeaters, picocells, femtocells, customer premise equipment, automotive compensators, cellular DAS, and wireless infrastructure applications.
