Abstract :
A cascaded filter design method is proposed and realized by combline topology for the flexible bandpass filters with tunable centre frequency and tunable bandwidth without the need for adjusting the inter-resonator couplings. This is achieved by cascading a quasi low-pass filter and a quasi high-pass filter, while minimizing interaction between the filters without the need for an isolator between the filters. Simulated results are presented.
