Low noise operational amplifier AD603ARZ solution verification board

Overview

This design is a debugging platform based on the low-noise operational amplifier AD603ARZ.
The AD603 is a low-noise, voltage-controlled amplifier for use in radio frequency (RF) and intermediate frequency (IF) automatic gain control (AGC) systems. It provides precise pin-selectable gain ranging from -11 dB to +31 dB at 90 MHz bandwidth and +9 dB to +51 dB at 9 MHz bandwidth.
This project uses the AD603ARZ-REEL7 (product number: C9815) from Lichuang Mall to design this verification board. The power supply is led out and the gain can be changed by adjusting the variable resistor. Some resistors can be short-circuited or not soldered, which is convenient as needed. debug.
This verification board can facilitate early debugging by R&D personnel and is for reference only.
