Design of a L-band Airborne Transceiver

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 d Bc. The gain of receiving channel is up to 85 d B,the noise figure is ≤3 d B,and the dynamic range is ≥65 d B. The result shows that the transceiver has stable performance and very strong practicability in flight test verification.
