Power amp targets multicarrier transmitters

A broadband power amplifier, the GRF5112 from Guerrilla RF, provides enhanced compression performance over large fractional bandwidths of up to 40%. The device’s broad single-tuned responses enable multicarrier base stations to simultaneously transmit across two or more cellular bands using a single RF lineup.

The GRF5112 GaAs pHEMT amplifier can be tuned over select bands within a frequency range of 30 MHz to 2700 MHz. At a frequency of 1.8 GHz, the amplifier provides a gain of 17.1 dB, OP1dB compression of 32.2 dBm, OIP3 linearity of 40 dBm, and a low noise figure of 1.7 dB when measured on the device’s standard evaluation board. De-embedded noise figure values are approximately 0.2 dB lower.

“Building upon the GRF5115 core, this latest iteration streamlines tuning while ensuring consistent performance across process and temperature variations. Our design team has also integrated additional tuning handles within the core to optimize linearity for specific bands and bias conditions,” said Jim Ahne, vice president of marketing at Guerrilla RF.

Like other GRF amplifier cores, the GRF5112 features a flexible biasing architecture that allows customizable tradeoffs between linearity and power consumption. Supply voltages can vary between 1.8 V and 5.25 V.

Prices for the GRF5112 in a 3×3-mm QFN-16 package start at $1.47 in lots of 10,000 units. Samples and evaluation boards are now available.
