Abstract :
A miniaturized end-coupled bandpass filter is realized by /spl lambda//4 hair-pin coplanar resonators. Attenuation poles at both sides of the passband are generated by a resonator arrangement to make a multi-pass circuit. The trial filter has 590 MHz 3 dB-bandwidth at 5.8 GHz and the insertion loss is 3.8 dB. The size is 3.5/spl times/3.75/spl times/0.4 mm/sup 3/. It is applicable to MCM (multi-chip-module) using bare-chip mount.
