抄録(英) The need for multiband RF front-end in modern communication system is growing rapidly. For example, satellite system always uses a complex arrangement of frequency plans and consequently needs filters for each communication channel and it will be ideal to have a single filter module that does jobs of all those channel filters to reduce the size and payload of the system. Also, multiband satellite terminals are calling for small and mobile sets as opposite to traditional large ground station, and therefore demanding not only multiband filters, but also miniaturized ones that can be easily integrated with antennas. In this paper, we propose a two-port balanced dual-band bandpass filter based on stepped impedance resonators. The resonance frequency and the bandwidth of the first harmonic band can be controlled by using the impedance ratio of stepped impedance resonator and the coupled spacing between stepped impedance resonator and extra open-loop resonator, respectively. For a front-end application the four-port balanced dual-band bandpass filter was presented. In order to extensively utilize the advantages of the small-size and light-weight of that, it may be more useful if the four-port may be transformed into a two-port. The two-port bandpass filter which may be transformed from the four-port balanced bandpass filter by the balun is proposed. The two-port balanced dual-band bandpass filter which has the input/output baluns and the fundamental frequency at 2.5 GHz and the first harmonic frequency at 5.5 GHz is fabricated and measured. Good agreement between measured and simulated results was achieved.
