Paper Abstract

A broadband microwave frequency division diplexer using photonic bandgap structure to improve the isolation and enhance output power level for tow-way electro-optic probe is presented. The microwave frequency division diplexer, where the lower pass-band is from 384 MHz to 2.58GHz and the upper pass-band is from 2.78 GHz to 8.55 GHz, is realized to connect two microwave circulators operated in different frequency band. Because of the compact size and easy to use for electrical probe, only four microwave circulators operated in different bands and three frequency division diplexer are considered to implement a planar electrical probe. Considering the ease of fabrication for wider ranges of realizable impedance values, easy to integrate with lumped-elements, small dispersion, and simple realization of series and shunt circuit elements, the coplanar waveguide structure is utilized to design and implement the proposed microwave frequency division diplexer. The simulated results of proposed microwave frequency division diplexer and experimental data of the wideband microwave frequency division diplexer with the circulators are presented and discussed in this paper.
