DESINING T/R MODULE FOR ACTIVE PHASED ARRAY RADAR

摘要

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