Receiver Electronics for Axion Experiment at CAPP

Abstract

The CAPP/IBS aims to do an axion search by detecting the axion using a resonant cavity. In this experiment, the axion signal should be amplified and down-converted because it is very weak (10-24 W) and the frequency is very high for digitization (2 8 GHz). In the radio frequency (RF) signal processing at room temperature, the amplifier and mixer play a crucial role. One of the amplifiers and the mixer is tested. Also the entire RF signal processing system is tested with a very weak artificial signal (10-19 W).
