Guerrilla RF has brought out its first two InGaP HBT power amplifier products.

Both devices deliver 60% saturated efficiency, with high gain and high output power – making them ideal choices for the final stage of applicable transmit chains.

GRF5504is 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.

GRF5509is 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 (3mm x 3mm), with identical pinouts 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.
