poor swr
Everyone,
I am having a few issues with the Rx side of the FDM system.
Configuration:
Input --------- Combined Channels ----------->
1-to-8 Divider ------> Filter (each output)
---------> Amplifier (each output) ----------> Mixer -------> Filter (Each output)
------> Output (Individual Channels)
I get like a 7:1 SWR at the input side. (Used a PNA 1-port measurement)
Any thoughts on the Rx configuration that can help with a better results. The individual components are good on paper but as a system I am seeing issues.
Any way to get a closer to 1:1 SWR at the input? Recommendations on what to measure is also welcomed.
Thanks.
