本文介绍一种新型的单脉冲雷达接收机前端,它采用微波混合集成电路。从天线到中频放大器的全部微波元件——限幅器、场效应管放大器、隔离器、镜象抑制混频器及前置中频放大器组装在一只盒子里,称为微波组件。由于此组件中各微波元件之间的联接不采用同轴电缆和接头,提高了微波系统的稳定性和可靠性。本文着重介绍了场效应管放大器、镜象抑制混频器和前置中放达到的性能指标:场
This article describes a new monopulse radar receiver front end, which uses a microwave hybrid integrated circuit. All microwave components - the limiter, FET amplifier, isolator, image reject mixer, and front IF amplifier, from the antenna to the IF amplifier, are housed in a box called a microwave module. As the microwave components in this component of the connection between the coaxial cable and connectors do not use, improve microwave system stability and reliability. This article focuses on the FET amplifier, the image suppression mixer and the pre-release to achieve the performance indicators: field
