摘要
介绍了一种S波段和X波段双波段复合式双极化T/R组件的研制方法和关键技术。该T/R组件两种波段接收和发射,而每个接收和发射各有2个通道,总共8个收发通道。对在较小的空间内实现多个波段的多路收发所带来的工作通道的复杂性以及由此带来的互不干扰的电磁兼容性和散热设计进行了分析和阐述,同时在每个波段的发射通道上加入Lange电桥,使得每个波段的2个发射通道的相位相差90°,可以使该组件实现双极化发射。测试结果表明该T/R具有组件双频带、高功率发射、双极化、体积小等特性。
This paper introduces the design and key technologies of S-band and X-band dual-polarized T/R module,T/R module has two kinds of transmitting channel and receiving channel wave band,each ransmitting channel and receiving channel each have two passage,totally has eight passage.Multi-channel transceiver of multiple bands in a small space work arising from the complexity of the channel and the resulting electromagnetic compatibility design and deat dissipation interfering analyzed and explained,while adding Lange bridge on each band transmission channel,so that the phase of each band of two ransmitting channels of 90°displacement,the component can realize the dual polarization transmission.Test result enunciation should the T/R have double waveband,big power transmitting,dual-polarized and the physical volume small characteristic.
