Design and Implementation of a L-band Miniaturized T/R Module
For the lightweight and miniaturized application requirements to high-power T/R components of active phased array radar system,a L-band miniaturized T/R module is designed by micro-assembly circuit and chip circuit technologies.The RF transceiver switching uses the double junction circulator,the transmission channel uses the Zero-IF modulation scheme,and the reception channel uses superheterodyne frequency conversion scheme.Through high-density micro-assembly integration process,the T/R module implements high-density integration of functional circuits of power division and amplification of LO,power amplification,low noise amplification,filtration,power supply modulation,power detection and so on.The batch trial-production verification shows that the output power of three-temperature transmission of this module is better than 49 dBm,the gain flatness of reception channel is better than±1 dB,the noise factor of three-temperature is better than 2.8 dB,the size is 75 mm×42 mm×20 mm,and the mass is about 130 g.
