Guerrilla RF releases initial power amplifier products

Guerrilla RF, a leading provider of high performance RFICs and MMICs, has introduced two InGaP HBT power amplifier products.

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

The GRF5504 is a high efficiency power amplifier that delivers up to 3.5W at Psat, with Vcc set to 5.0V 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 GRF5509 is another high efficiency power amplifier. It delivers 4W OP1dB, with Psat approaching 5W 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. In addition, high linearity tunes for each part deliver OIP3 numbers greater than 45 dBm.

According to Research and Markets, the overall wireless network infrastructure market will witness tremendous growth over the next few years. At a compound annual growth rate of over 5 percent, the market will account for over $104 billion in annual spending by the end of 2020.
