Ultra-Wideband Multiprobe Reflectometer Designed in MMIC Technique

A new ultra-wideband multiprobe reflectometer designed in MMIC technology is presented in this paper. To verify usefulness of the proposed design in integrated circuits applications, the UMS PH25 technology has been utilized. The presented reflectometer is composed of two transmission lines connected in parallel, and six resistive probes arranged non-uniformly, what increases operational bandwidth of the device. Due to the fact that in such a technique the dimensions limitation must be considered, a meander shape has been implemented. The proposed reflectometer operating in the frequency range 1. 02 - 60 GHz has been designed and verified.
