A Photonics-Based Superheterodyne RF Reception Approach

A novel photonics-based RF reception approach is proposed as a competitive solution to meet the current challenges of approaches and realize high performances at same time. The adopts superheterodyne configuration by combination manner electronic techniques photonic techniques, including ultra-wideband generation optical LO, two-stage frequency conversion real-time IF compensation. An engineering prototype has been developed its performance evaluated in laboratory environment. experiment results preliminarily verify feasibility potential. typical are follows: 0.1 GHz ~ 45 operation spectrum range (> 40 GHz), 900 MHz instantaneous bandwidth, 101 dB·Hz2/3 SFDR 130 dB·Hz LDR, image rejections 80 dB for 1st > 90 2nd conversion.
