0.25-W InGaP HBT power amplifier provides 24 dBm of output power
InGaP HBT power amplifier provides 24 dBm of output power for cellular applications requiring high native linearity over temperature extremes.

During the development of the GRF55xx series, Guerrilla RF consulted directly with its base of customers to ensure the devices delivered the best blend of power and linearity, thus maximizing the effective range and throughput for their cellular systems. Guerrilla RF also designed the entire family of devices to be fully footprint compatible, enabling its customer base to rapidly customize their designs for a myriad of cellular frequencies.

When describing the motivation behind the GRF5507’s development, Ryan Pratt, CEO and founder of Guerrilla RF, stated, “The GRF55xx family builds upon the groundbreaking work which we started a year ago with the release of the GRF5504/9 series of 5-W InGaP HBT power amplifiers. These new ¼ W PAs were created specifically to meet the needs of our strategic customers in the cellular and automotive industries. Together with the original GRF5504/9 series, the GRF55xx family will serve as the beachhead for Guerrilla RF’s expansion into the growing power amplifier market.”

The GRF55xx family comes in pin-compatible 3- x 3-mm, 16-pin QFN packages. The common footprint enables a single design to address multiple bands via simple component swaps.
