Power amplifier products offer industry-leading saturated efficiency
Guerrilla RF, Inc., has introduced its first two InGaP HBT power amplifier products. 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.

GRF5504 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.

GRF5509 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 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.

“Guerrilla RF is proud to introduce our first InGap HBT power amplifiers to the market. The industry-leading saturated efficiency and high output power address a need for cost-effective discrete solutions that deliver strong, consistent performance over flexible operating conditions. These amplifiers provide exceptional and consistent performance at very competitive prices,” said Ryan Pratt, CEO and Founder of Guerrilla RF. 

According to Research and Markets, the overall wireless network infrastructure market will witness tremendous growth over the coming 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.

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