Broadband pre-driver power amplifier for multicarrier base stations
Guerrilla RF has announced the formal release of its highly linear GRF5112 broadband power amplifier, which excels in delivering excellent compression performance over large fractional bandwidths of up to 40 percent.
The GRF5112 pre-driver power amplifier boasts broad, single-tuned responses that enable multicarrier base stations to simultaneously transmit across two or more cellular bands using a single RF lineup.
“The GRF5112 power amplifier is another example of Guerrilla RF constantly working to improve its driver amplifier offering,” says Jim Ahne, vice president of marketing at Guerrilla RF. “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 power amplifier 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, 40 dBm of OIP3 linearity, and a low noise figure of 1.7 dB (as measured on the device’s standard evaluation board; de-embedded NF values are approximately 0.2 dB lower). 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.
Packaged in a compact 3- x 3-mm QFN-16 package, the GRF5112 pre-driver shares a pinout and matching layout with many of the company’s linear drivers and power amplifier cores. Samples and evaluation boards are available.
