Design of a Highly Integrated Front-End K-Band TR Module Based on LTCC Technology for Phased-Array System

摘要

A novel highly integrated front-end TR (Transmit-Receive) module with four RF (Radio Frequency) channels for the application of a K-Band transceiver is introduced. The housing cavity of the proposed TR module is based on the LTCC (Low Temperature Co-Fired Ceramics) technology with embedded passive RF circuit, control signal circuit and bias power supply circuit. Due to the employing of the LTCC technology, it allows to reduce the overall size and weight of the designed TR module. Furthermore, such design improves the overall performance of the TR module with a lower cost and high efficiency.
