摘　　要：单片式西沙瓦波(Seza wa)卷积器是信号处理的重要器件。本文对西沙瓦波卷积器的基本原理、主要设计参数作了描述,给出了我所研制的西沙瓦波卷积器的测试结果,并对器件的性能改进作了讨论。The monolithic Sezawa convolvers are a kind of important devices for processing signals. This paper described the principle or Sezawa convolver and its main design parameters,and gave the measured results of Sezawa convolver with f0=76MHz, Fr= -61dBm, which has been developed in our institute. Moreover, the paper had a discussion on the improvement of device performances.
