Broadband frequency filtering and mode‐matching transition using finline technology for high‐frequency nonlinear electronic applications is proposed. Based on homemade code and full‐wave three‐dimensional electromagnetic simulations, the validity of the concepts are assessed on a prototype aimed at operation between 18 and 26 GHz. Results show that very good performance (less than −0.5 dB for the insertion loss of the taper, as well as a rejection higher than −20 dB for the filtering action) can be maintained over the 30% bandwidth required for future space applications. © 2004 Wiley Periodicals, Inc.
