Abstract

This paper describes the design and fabrication of a high power amplifier which is a component of TDL(Tactical Data Link) aircraft terminal. We applied high-speed frequency hopping technology, cognitive radio technology, and receive filter bank technology to efficiently use limited frequency resources with radar and other communication equipment using the same frequency band. The high-power amplifier is physically composed of a transmitter, a receiver, a mechanical part, and a cable assembly, and is designed to meet temperature characteristics and electrical characteristics such as maximum transmission distance and reception sensitivity. Modeling and simulator were used to satisfy the requirement of high power amplifier. The transmit power and the noise figure were measured at 50.02dBm and 2.682dB, respectively. It was confirmed that all the required specifications were satisfied in the electrical characteristics test and the environmental characteristic test.

본 논문은 TDL(전술 데이터 링크)의 항공용 단말의 구성품인 고출력증폭기의 설계 및 제작에 관해 기술하였다. 동일한 주파수 대역을 사용하는 레이다 및 다른 통신장비와 한정된 주파수 자원을 효율적 사용이 가능하도록 고속주파수도약기술, 인지무선기술, 수신필터뱅크 기술을 적용하였다. 고출력증폭기는 물리적으로 송신부, 수신부, 기구부, 케이블조립체로 구성되며, 최대 전송 거리, 수신감도 등의 전기적 특성과 온도 특성을 충족하도록 설계되었다. 고출력증폭기의 요구 규격을 만족하기 위해 모델링 및 시뮬레이터를 이용하였다. 송신 출력과 잡음 지수는 각각 50.02dBm 및 2.682dB로 측정되었다. 전기적 특성 시험 및 환경 특성 시험으로 요구 규격을 모두 만족함을 확인하였다.
