Guerrilla RF, Inc., a leading provider of high performance MMICs, is pleased to announce the introduction of our family of 5GHz low noise amplifiers. The GRF25xx family is a series of ultra-low noise amplifiers (LNAs) designed for IEEE 802.11a/n/ac applications in the 5GHz band (4.9GHz to 5.95GHz). These devices exhibit best-in-class noise figures (NFs) as low as 0.6 dB across the band, along with excellent gain and high linearity. Furthermore, they can be biased with Vdd from 2.7 to 5.0 volts with adjustable current to suit linearity requirements.

Guerrilla RF's GRF25xx family of LNAs are operated from a single, positive supply voltage and are internally matched to 50Ω at the input and output ports. These products are available in an industry-standard 6-pin DFN package (1.5mm x 1.5mm). In addition, the GRF2561 is available with our patented Guerrilla Armor™ technology. Guerrilla Armor™ is a proprietary architecture for insuring high off-state isolation for the LNA under high RF input power level conditions.

The GRF25xx series will be available for engineering evaluation in June of 2014.
