Abstract:

According to the request of small dimension,light weight and low power consumption for airborne equipment,an L-band transceiver working in TR time division system is designed by using RF circuit miniaturization and integration technology,high-efficiency power amplifier technology,and integrated rapid AGC technology.The appearance is 65 mm×65 mm×20 mm in size,130 g in weight,and less than 6 W in power consumption.The output power of transmitting channel is≥6 W,and the third-order intermodulation is≤-18 dBc.The gain of receiving channel is up to 85 dB,the noise figure is≤3 dB,and the dynamic range is≥65 dB.The result shows that the transceiver has stable performance and very strong practicability in flight test verification.
