Abstract :
High power and temperature stable "Channel Dropping Filters" for Transmission Multiplexer of base stations have been miniaturized to almost 1/3 the size of the dielectric TM/sub 010/ resonator filter by using triple mode resonance, and we reported on this at the last symposium. The triple mode resonator works as resonators of three independent one-section filters. The isolation level between each two filter was about 40dB.
