Introduction of variable gain video tributary amplifier controlled by electronic circuit

RF cable can be customized for other specifications

The variable-gain video tributary amplifier controlled by the electronics uses the LT1228 transconductance amplifier in this application circuit, and the gain is adjustable from -12 to +8dB.
Variable Gain Amplifier is a gain, DC-coupled amplifier with differential input, single-ended input, high input impedance, and high common-mode rejection ratio
