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.

High Quality PCB >> INCLUDES WITH DOCUMENT

I was pleasantly surprised by the high quality of the circuit board. Received ahead of scheduled delivery date (via Revain). Well designed RF circuit with curved traces for use on HF/VHF frequencies. The seller provided documentation in the form of a schematic diagram and a picture of the circuit board at a competitive price. I honestly didn't expect any documentation with a board from China. The seller even provided mounting hardware! Overall very pleasantly surprised! I'm not sure why it's…

Pros
  • It provides precise pin-selectable gain from 11dB to +31dB at 90MHz bandwidth, +9dB to +51dB at 9MHz bandwidth, and every gain range in between with an external resistor.
Cons
  • Little things
