AD603 Voltage-controlled Gain Amplifier Module VCA -20~60dB Gain High Bandwidth Low Noise Amplifier

AD603 Voltage-controlled Gain Amplifier Module VCA -20~60dB Gain High Bandwidth Low Noise Amplifier

Description:
- The module adopts AD603 design, which is a low noise, voltage controlled amplifier chip. According to different circuit configurations, the AD603 has three operating modes: -10~30dB (bandwidth 90MHz), 0~40dB (bandwidth 30MHz), and 10~50dB (bandwidth 9MHz). The circuit design of this module is in the -10~30dB (bandwidth 90MHz) operating mode, using two AD603s to form a two-stage amplifier circuit, allowing its gain range to reach -20~60dB. There are two gain control methods available: potentiometer adjustment or external input voltage control. Provide bias adjustment potentiometers. The module has excellent performance and can be used in the VCA part of RF and IF automatic gain control (AGC) systems, as well as in video gain control, analog-to-digital (A/D) range extension, signal amplification, and signal measurement systems.

Package Included:
- 1 x Gain Amplifier Module
