GRF5507

The GRF5507 from Guerrilla RF is a high-gain, two-stage InGaP HBT power amplifier designed for the 700 to 800 MHz band, with an extended range up to 0.91 GHz. It delivers exceptional P1dB, ACLR, and IM3 performance, making it suitable for transmitter applications that do not utilize digital predistortion correction.

Key electrical specifications include a typical gain of 30.5 dB at 750 MHz, a typical output power of +24.5 dBm, and an OIP3 of 47.3 dBm at +23 dBm POUT/tone. The device maintains +24 dBm linear output power at 85 °C and features flexible biasing for linearity optimization. It operates with a 5 V supply voltage and has a native mode quiescent current consumption of 195 mA.

The GRF5507 has a rugged design resilient to mismatched loads and operates over a temperature range of -40 to 85 °C. It features single-ended 50 Ω input and output impedances and includes a digital shutdown pin for control. The amplifier is housed in a compact 3 x 3 mm QFN-16 package, suitable for surface mount applications.

This amplifier is part of a family of externally matched linear amplifiers covering various frequency ranges, designed for applications such as cellular boosters, automotive compensators, picocells, femtocells, cellular DAS, customer premise equipment, and general wireless infrastructure.
