Wideband Downconverter System Design and Simulation

Wideband downconverters are used in electronic warfare (EW) systems and the performance is critical to the overall performance of the system. This paper describes the design of a miniature wideband downconverter that has to meet stringent RE performance requirements as part of a broadband digital receiver. The trade offs between space, filtering and component performance are highlighted. Using system simulations that use computer aided design techniques the performance of a downconverter system has been simulated and compared to measurements.
