Guerrilla RF introduces power amplifier range

Claimed to be industry-leading power amplifiers, InGaP HBT power amplifiers are designed for GPS, RFID, ISM and automatic meter reading applications, says Guerrilla RF.

The company has introduced the first two InGaP HBT power amplifiers. Both devices deliver 60 per cent saturated efficiency, with high gain and high output power, suitable for the final stage of applicable transmit chains.

The GRF5504 delivers up to 3.5W at Psat, with Vcc set to 5.0V and a low Iccq of 120mA.  PAE at Psat is around 64 per cent and the device can be tuned over a range of frequencies from around 400 to 500MHz, with typical fractional bandwidths of three to five per cent.

The GRF5509 power amplifier delivers 4.0W OP1dB, with Psat approaching 5.0W with Vcc at 5.0V and a low Iccq of 125mA. PAE at Psat is 58 per cent. The GRF5509 can be tuned over a range of frequencies from around 700 to 1,000MHz, with typical fractional bandwidths of three to five per cent.

Both the GRF5504 and GRF5509 are supplied in the QFN-16 package, which measures 3.0 x 3.0mm, with identical pinouts and flexible biasing for both voltage and current.  High linearity tunes for each part deliver OIP3 numbers greater than 45dBm.

According to Ryan Pratt, CEO and founder of Guerilla RF: “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.

“The GRF5504 and GRF55094 are our initial power amplifier product offerings utilizing InGaP HBT,” he said, adding that there will be additional announcements over the next 12 months.

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