摘　　要：报道了我们研制的一种采用声表面波信道化技术的随机带阻滤波组件。该组件输入、输出驻波不大于1.8,插入损耗不大于22dB,阻带抑制不小于70dB,信道全通工作时通带波动不大于5dB。该组件可在一定程度上提高通信系统的抗干扰能力。The present paper reported the primary study on random bandpass and band-rejection filter module utilizing surface acoustic wave channelized technology. The performances of this module were as follows: input and output standing wave ≤1.8; insertion loss ≤22 dB; ultimate rejection ≥ 70 dB; passband variation ≤ 5 dB while all channels were on. It could be concluded that this module can improve the anti-jamming ability of communication system.
