본논문은AESA 레이다용송수신모듈(Transmit Receive Module, TRM)의 송수신 성능 검증을 위한 새로운 측정방법에대하여 기술하였다. 일반적인 AESA 레이다용 송수신모듈은 송신과 수신이 구조적으로 분리되어 있기에 내부신호에의한간섭문제가적으며해결이용이하였다. 하지만최근개발되는송수신모듈은SiP(System in Package)를이용한소형/ 집적화구조로송신과수신이통합됨에따라송수신동시운용시내부신호의간섭에따른송수신성능을검증할필요성이있다. 또한기존자동화측정장비는송수신성능시험이별도로구성되어내부신호간섭영향성을확인하기어려웠다. 따라서 송수신 동시운용시험이가능한송수신검증자동화측정장비를설계및제작하였고, 이를통해내부신호 간섭영향성을고려한송수신모듈성능을실험적으로검증하였다.

This paper presents a novel measurement method for evaluating the transmit/receive performance of the transmit/receive modules (TRMs) in active electronically scanned array (AESA) radar systems. Conventional TRMs structurally separate the transmitter and re ceiver, minimizing internal signal interference and simplifying performance verification. However, a recently developed TRM utilizes system-in-package (SiP) to achieve a compact and integrated structure. The transmitter and receiver are integrated, necessitating the ver ification of the transmit/receive performance so as to address the interference of internal signals during simultaneous transmission and reception. Moreover, because conventional automated measurement equipment are limited to testing the performances of the transmitter and receiver separately, assessing the influence of internal signal interference is difficult. Therefore, an automated measuring equipment capable of simultaneously testing the transmitter and receiver operations is proposed. Experimental verification of the performance of the integrated TRM, accounting for the influence of internal signal interference using the proposed equipment, is presented.
