Solid-State T/R Module Design and Modeling for Radar Applications

Active phased-array radars (APARs) typically require solid-state T/R modules with high-output power, low NF, high TOI, and sufficient gain in order to function properly. Since the T/R module is 40-60% of the overall RF front-end cost, it is imperative to use an architecture that meets all requirements with the most cost-effective technology, such as MMICs, and a minimal bill of materials. This article overviews various solid-state semiconductor technologies for T/R module development and describes a design methodology that includes the modeling/analysis of a T/R module.
