This paper presents the design and characterization of a miniaturized tunable bandpass filter utilizing high-Q ceramic coaxial resonators and commercially available RF-MEMS tunable digital capacitors. A proof-of-concept 2-pole tunable filter occupying only 10 × 10 mm2 is demonstrated with a frequency tuning range of 800-1100 MHz and bandwidth tuning range of 6-13%.
