The Design of Four Channel TR Module for Ku Band

Abstract

This paper presents the design and development of four channel digital TR module for Ku band.The four channel TR module for Ku band consists of consists of digital part and RF part. DDS, TR control, AD, DDC and echo transmission constitute the digital transceiver part of the digital TR module. Two-stage frequency conversion and filtering, circulator, limiter, multi-stage LNA and multi-stage PA constitute the the RF transceiver part of the digital TR module. At present, the digital TR module has completed the program design, production and processing, testing.
