Potent Saturated Output Positions Gain Blocks for Wireless Apps

May 20, 2015
Guerilla RF's high-linearity, low-noise gain blocks, internally matched to 50 Ω, offer the saturated output power needed in wireless infrastructure applications

High-linearity, low-noise gain blocks developed by Guerrilla RF offer the saturated output power needed in wireless infrastructure applications such as small cells, cellular repeaters, LTE/WCDMA linear/saturated driver amplifiers, and high-power saturated power-amplifier (PA) drivers. The devices, internally matched to 50 Ω, only require external dc blocks and a bias choke on the output.

Specifically, the GRF2013 is configured as a linear driver or cascaded gain block. Operating from supply voltage of 2.7 to 8.0 V with a selectable IDDQ range of 30 to 100 mA, it exhibits return losses over 200 to 2700 MHz with a single match. The GRF3013 broadband SOT-89 gain block, a drop-in replacement for other more expensive standard gain blocks, is also configured as a linear driver or cascaded gain block. It exhibits return losses over 500 to 2700 MHz with a single match. Operating from a 5.0-V supply voltage, it delivers supply voltages from 3.0 to 6.0 V. Noise figure for both devices is 2.4 dB at 2.5 GHz, and operating temperature is to 105°C.
