325 to 500 GHz vector network analysis system

Abstract

This paper describes a novel and compact WR-02.2 millimeter wave frequency extension transmission/reflection (T/R) module for use with a vector network analyzer. The WR-02.2 T/R module extends the measurement capabilities of a microwave vector network analyzer to 500 GHz. Full 2-port S-parameter measurements with 40 dB or greater system dynamic range is realized in the 325 to 500 GHz frequency range. The stimulus millimeter wave signal is generated via multipliers with an external microwave synthesizer input. The reference and test response are down-converted to an Intermediate Frequency (IF) via millimeter wave harmonic mixers. The response is shown on the microwave vector network analyzer display.
