摘要：
A microstrip eight-channel diplexer with a compact size and a wide stopband is presented. There are sixteen stepped-impedance resonators controlling the passband characteristics. Every two resonators are used for one passband resulting in a high design freedom. There are four passbands filtered out at each of the two output ports. The circuit size is only 0.1 lambda(2)(g) at the lowest channel frequency. The isolation is more than 29 dB, and the 20 dB upper stopband extends up 8.22 x to the lowest operation frequency.
