可变增益放大器

Analog Devices’ variable gain amplifiers (VGA), IF variable gain amplifiers and variable gain control products offer the high performance requirements of the communications, instrumentation, and military designs. ADI’s VGA portfolio includes continuous analog linear and digital step controlled products that provide as fine as 0.25 dB step and linear in volts digital control. ADI’s highly integrated RF VGA work with digitally controlled multipole analog filters integrated on-chip and with AGC circuits for automatic level control.
