LLRFDwConv is responsible to down-convert the RF signal from the RF system components (such as cavity pick-up, Solid State Amplifier, Master Oscillator, circulator, and transmission line) to the Intermediate Frequency (IF) signal to be digitized by the main processor.
LLRFDwConv is an 8-channel down-converter that converts RF input signal (500MHz) to IF output signal (20MHz) by mixing with LO signal (480 MHz). Monitoring ports are provided in the Front Panel through SMA connectors. It requires a +5V DC power supply. The simplified diagram with the main components and ports is shown in Fig. 1.
