Stable RF signal distribution based on passive post phase correction with only one-stage frequency mixing

摘要

In this letter, we propose and demonstrate a phase stabilization approach to distribute a radio frequency (RF) signal from remote antenna to local station based on passive post phase correction. Simplified antenna structure makes our scheme cost-effective and easy to implement. The key advantage of our method is that only one-stage frequency mixing is used, which indicates simpler operation and less conversion loss. A proof-of-concept experiment verifies that the phase drift is effectively compressed using the proposed scheme compared to the free-running situation.
