摘要

介绍了有源相控阵雷达(APAR)的L波段和c波段收发模块的概念和性能。对发射机进行了最小透射率畸变和最大输出功率的优化。所采用的方法是基于自己发明的电热MESFET模型。根据输入功率的最小噪声系数和最大电阻对接收机进行了优化。T/R模块最重要的参数如下:l波段P/sub out/ = 100 W， /spl Delta/|T|<0.1 dB， /spl Delta/ /spl phi/<1/spl deg/， F<2.5dB;c波段P/sub out/ = 4 W， /spl Delta/|T|<0.1dB， /spl Delta/ /spl phi/<0.2/spl deg/， F<2.5dB。

Designing T/R module for active phased array radar

The paper presents the concept and the performances of the L- and C-band T/R module for an active phased array radar (APAR). The transmitters were optimized for minimum transmittance distortions and maximum output power level. The method used was based on a self-invented electro-thermal MESFET model. The receivers were optimized with respect to the minimum noise figure and maximum resistance for the input power. The most important parameters of the T/R modules are as follows: L-band with P/sub out/ = 100 W, /spl Delta/|T|<0.1 dB, /spl delta//spl phi/<1/spl deg/, F<2.5dB; and C-band with P/sub out/ = 4 W, /spl Delta/|T|<0.1dB, /spl delta//spl phi/<0.2/spl deg/, F<2.5dB.
