Variable Gain Amplifiers

Analog Devices RF VGAs, IF VGAs, and variable gain control products offer the high performance needed for communications, instrumentation, and military designs. The portfolio includes continuous analog linear in dB products based on X-AMP® interpolation architectures and digital step controlled products providing as fine as 0.25 dB step and linear in volts digital control. Furthermore, ADI RF VGAs are highly integrated with digitally controlled multipole analog filters integrated on-chip as well as AGC circuits for automatic level control.

Analog Control VGAs

Analog Devices voltage controlled variable gain amplifiers provide continuous gain control over a wide dynamic range for a variety of audio and optical frequency bands.

Baseband Programmable VGA-Filters

ADI RF VGAs, IF VGAs, and variable gain control products offer the high performance needed for communications, instrumentation, and military designs.

Digital Control VGAs

ADI digital controlled variable gain amplifiers provide discrete levels of gain control over a fixed number of control bits for a variety of audio and optical frequency bands.
