Abstract:
A cavity filter having two series of resonance chambers bilaterally connected between an antenna port and two opposing signal input/output ports, each series of resonance chambers having the last resonance chamber thereof connected to the antenna port and the first resonance chamber thereof connected between the respective signal input/output port and the associating last resonance chamber to perform cross-coupling feedback, improving the quality of the signal received by the signal receiver using the cavity filter and enhancing signal transmission performance.
