Abstract :
This paper focuses on the design of a microstrip parallel-coupled filter with cross coupling to suppress the spurious passband at 2f O. The authors combine the over-coupled method and high image impedance method to suppress the 2f O spurious passband and use cross coupling method in to generate finite transmission zeros.
