Application Note

Design and Implementation of a Miniature X-Band Edge-Coupled Microstrip Bandpass Filter

This application note presents a straightforward and largely nonmathematical method for designing an edge-coupled, bandpass filter for X-band operations (8.4- 9.3 GHz) with a combination of filter synthesis, closed-form edge-coupled transmission-line models, and EM analysis using the Microwave Office circuit simulator.
