Low dielectric substrates for MIC's at millimeter wave frequencies

Abstract

Microwave Integrated Circuits (MIC) have been extended to the millimeter wave frequencies by using low dielectric substrates and by adapting circuits for thick copper conductors. The paper describes the performance of MIC polar discriminators for the K and Ka bands and other printed circuits developed for a channelized downconverter. The MIC designs have small size, high performance and very low manufacturing costs.
