GRF releases new broadband pre-driver for wireless infrastructure
Guerrilla RF has announced the release of its new GRF5112, a highly linear, broadband power amplifier that delivers excellent compression performance over large fractional bandwidths of up to 40vpercent.
The GRF5112’s broad, single-tuned responses enable multicarrier base stations to simultaneously transmit across two or more cellular bands using a single Kr lineup.
“The GRF51 12 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 GRFS1 IS 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 optimise 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 OPIdB 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 N values are approximately 0.2dB lower).
Like other GRF amplifier cores, the GRF5112 features a flexible biasing architecture allowing customisable 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 x3 mm QFN-16 package, the GRF51 12 shares a pinout and matching layout with many of the company’s linear drivers and power amplifier cores.
