Digital Variable Gain Amplifiers (DVGA’s) GRF6411/GRF6412

Jim Ahne, Senior Vice President of Marketing at Guerrilla RF, provides a deep dive into the company’s Digital Variable Gain Amplifiers (VGAs) — devices designed to blend high linearity, amplification, and fine-grained digital control into one compact RF solution. • The architecture of Guerrilla RF’s VGAs and how they combine a gain block with a digital step attenuator (DSA) for seamless gain control • The unique Rapid Fire™ capability — enabling ultra-fast toggling between preset attenuation states, useful for handling blockers and protecting A/D inputs • Key performance targets: wide frequency coverage, fine step resolution, low insertion loss, and high linearity • Use-case scenarios: protecting receivers in telecom, satcom, radar, and high-dynamic-range front ends • Deployment guidance: interfaces, control schemes, and system-level considerations Guerrilla RF’s digital VGA line is embodied in their GRF6411 / GRF6412 products, which integrate a high-performance gain element and a DSA into a single device.
