A filter with wide bandwidth and high impedance for China mobile multimedia broadcasting (CMMB) has been reported in this paper. The filter uses a ladder type SAW notch network and high pass LC filter network structure. The principle circuit is constructed by using XTAL2 equivalent model of SAW resonator and Murata inductive components. The frequency response of filter is obtained through integrated simulation optimization within ADS. The insertion loss of pass band is less than 2.0dB, the stop band rejection is better than 43dB, and the frequency selection is very well.
