Abstract :
Conventional microwave transversal filters are hindered by bandwidth limitations and cannot provide long-time delays due to excessive propagation losses. Optical transversal filters lack the means to provide negative weighting coefficients. Therefore, a hybrid transversal filter that utilizes low loss, wide bandwidth optical fibers for the delays and microwave monolithic integrated circuits (MMIC´s) for accurate weighting is investigated. Theoretical analysis of the noise performance, bandwidth, and delay fine dispersion of a completed MMIC advanced transversal filter and the novel hybrid transversal filter are presented
