This paper reports on the design, fabrication and performance of a third-harmonic fixed-tuned frequency mixer, working at W-band frequencies. The mixing circuit consists of a variation of crossbar structure, a combination of the suspended stripline circuit and the microstrip matching circuit. The mixing diodes are arranged as a single balanced configuration near the end of the RF waveguide. The precise...
A compact scheme for stable frequency dissemination over optical fiber is proposed and demonstrated. A standard signal in the center station is delivered to the remote end without any assistant signal source. The frequency of the received signal is the same as the signal source in the center station. A proof-of-concept experiment is performed. A 6-GHz standard signal is transmitted in a 20-km fiber...

The transfer of radio frequency (RF) signal via optical fiber is widely used in distributed antenna systems. To compensate the phase variation caused by fiber length fluctuation, passive phase correction technique is proposed with obvious advantages over the traditional active phase correction method. This paper reviews the recent developments of the stable RF transfer based on passive phase correction...
A simple, compact, cost-effective post-phase correction method for stable fiber transfer of RF signal is proposed and demonstrated. By employing only one LO source and two frequency mixers, a RF signal is transmitted to the local station with very small phase jitter. An experiment is performed. When a 6-GHz RF signal is delivered through a 20-km SMF, effective cancellation of the phase jitter induced...
