“The GRF5112 is another example of Guerrilla RF constantly working to improve its driver amplifier offering,” says
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, 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 0.2dB 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 shares a pinout and matching layout with many of the company’s linear drivers and power amplifier cores.
