Guerrilla RF Releases New Power Amplifier Products with Superior Saturated Efficiency

Guerrilla RF has announced the release of its first two InGaP HBT power amplifier products, the GRF 5504 and GRF 5509. Both devices deliver 60 percent saturated efficiency, with high gain and high output power – making them ideal choices for the final stage of applicable transmit chains.

The GRF 5504 is a high efficiency power amplifier that delivers up to 3.5 W at Psat, with Vcc set to 5.0 V and a low Iccq of 120 mA. PAE at Psat is roughly 64 percent and the device can be tuned over a range of frequencies from around 400 MHz to 500 MHz, with typical fractional bandwidths of 3 percent to 5 percent.

The GRF 5509 is another high efficiency power amplifier that delivers 4 W OP1dB, with Psat approaching 5 W with Vcc at 5.0 V and a low Iccq of 125 mA. PAE at Psat is 58 percent and this part can be tuned over a range of frequencies from around 700 MHz to 1000 MHz, with typical fractional bandwidths of 3 percent to 5 percent.

Both devices are supplied in the QFN-16 package (3-mm x 3-mm), with identical pin-outs and flexible biasing for both voltage and current. Additionally, high linearity tunes for each part deliver OIP3 numbers greater than 45 dBm. These notes for optimal IP3/IMD/ACLR performance in linear applications can be found on the company’s website, under the landing page of the individual part number.

Samples and evaluation boards are available now for both devices, with production planned for late Q3/early Q4 2019.
