HIGH-PERFORMANCE COMMUNICATION VARIABLE
GAIN-CONTROL AMPLIFIER MODULE
HVGC SERIES
HVGC series amplifiers provide continuous gain adjust with the application of external control voltage. These
amplifiers are used in IF transmit/receive chains to enable the user to adjust the gain as necessary to compensate
for the insertion loss of the integrated modules. Optionally, the gain variation versus control voltage can be lin-
earized (dB/volt) through the entire dynamic range for customized applications.
FEATURES
• Excellent passband gain flatness
• Wide input dynamic ranges available
• Low noise figure
