The GRF5617 from Guerrilla RF is a Two-Stage Power Amplifier that operates from 1710 to 1785 MHz. It provides a small signal gain of 25.1 dB and maintains a linear output power of 26 dBm at 85°C. This amplifier is based on InGaP HBT technology and provides excellent P1dB, ACLR, and IM3 performance. The high linearity of this amplifier makes it an ideal choice for transmitter applications that typically do not employ digital pre-distortion correction schemes. It requires a DC supply of 5 V and consumes less than 650 mA of current. This amplifier is available in a compact QFN-16 package that measures 3 x 3 mm and is extremely resilient to mismatched loads. It is ideal for cellular boosters, automotive compensators, picocells/femtocells, and customer-premise equipment applications.
