Description of AD603 Variable Amplifier Voltage Adjustable
Name: AD603 Voltage Controllable Gain VCA Module Size: 50mm X 39mm Supply voltage range: ±5v. This amplifier module is a voltage controllable gain amplifier. It is composed of two AD603 cascade amplifiers. It can amplify the signal voltage amplitude well. The gain can be adjusted up to 80dB. The AD603 is a low noise, voltage controlled amplifier for radio frequency (RF) and intermediate frequency (IF) automatic gain control (AGC) systems. It provides accurate pin selectable gains from 11 dB to +31 dB at 90 MHz bandwidth, +9 dB to +51 dB at 9 MHz bandwidth, and any intermediate gain range with an external resistor . Chip application RF / IF AGC Amplifier Video gain control Modulus Range Extended Signal Measurement.
