Telecom equipment manufacturer Guerrilla RF, Inc. (GRF) announced the release of its new GRF5112, a linear, broadband power amplifier designed to deliver compression performance over large fractional bandwidths of up to 40 percent. The GRF5112’s broad, single-tuned responses are engineered to enable multicarrier base stations to simultaneously transmit across two or more cellular bands using a single RF lineup.
“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.”
The GRF5112 can be tuned to operate over select bands within the 30 to 2700 MHz frequency range. When operated at 1.8 GHz, the device delivers 17.1 dB of gain, 32.2 dBm of OP1dB compression.
Like other GRF amplifier cores, the GRF5112 features a flexible biasing architecture allowing customizable trade-offs between linearity and power consumption. Supply voltages can vary between 1.8 and 5.25 V, although most customers will elect to use a standard 5V supply with 212 mA of biasing current.
