✦ Synopsis

The design of a narrowband MIC filter using the high-Q lumped resonators is presented. The unloaded Q-factor of the lumped resonator estimated by theory and experiment is about 150 at 2.44 GHz. A two-section bandpass filter prototype is designed and tested. This filter demonstrates a maximum insertion loss of 2.1 dB in the passband and a rejection greater than 30 dB in the stopband.
