Theory, Design and Performance of a Ring Circulator
نویسندگان
چکیده
A compact, symmetrical, three-port S-band circulator composed of reciprocal tee junctions andnonreciprocal phase shifters is investigated theoretically, and its experimental performance results are presented. The comparison of these results demonstrates that (1) circulators can be designed and their experimental performance described from a network model and (2) there is no theoretical limitation on the minimum amount of total differential phase shift necessary for perfect circulation. Bandwidth is investigated and techniques are discussed, including the introduction of a "backward wave" phase shifter, for achieving larger bandwidths. The stripline, nonreciprocal, comb-filter phase shifter used in the ring circulator is described and performance results are given. Accepted for the Air Force Franklin C.

متن کاملEnvironmentally stable, simple passively mode-locked fiber ring laser using a four-port circulator.
We present here a self-starting passively mode-locked fiber ring laser with a novel cavity configuration using a four-port optical circulator. Our special ring cavity design enables highly stable mode-locked operation between 25 and 60 degrees C to be maintained without the need for any polarization-adjusting devices. The pulse width and the integrated timing jitter from 10 Hz to 10 MHz of our ...

متن کاملDesign and Analysis of 4-GHz SOP FMCW HMIC Radar
The demand for higher performance systems that are smaller and have the potential to be more cost effective has lead hardware designers to adopt integration of many components and modules in a package (SOP) or on a chip (SOC). A compact SOP (single-substrate) L-band FMCW HMIC radar module for high-resolution sensor application has been demonstrated. For use with a single transmitreceive antenna...
