600-MHz-1.2 GHz High-Power Tunable RF-MEMS Filters

Abstract : In this paper, a two-pole tunable bandpass filter with flexible tuning capabilities and wide tuning range are proposed. By adding tuning elements at the ends of the resonators, the resonant frequencies can tuned, The measured results show that when the central frequency was shifted from 1130MHz to 690MHz, the tunable filter exhibits insertion loss is from 1.7dB at 1130 MHz to 3.3dB at 690 MHz and the constant bandwidth is 65MHz+/-5MHz, and matching is better than -12dB. The filter shows no compression up to 1Watt of input power, and no measurable degradation of ACPR at the same power level.
