Abstract: A radio frequency switching apparatus wherein a filter for a transmitter module passes a transmission frequency to an antenna in a transmission mode and isolates the antenna and the transmitter module from each other in a reception mode. The radio frequency switching apparatus comprises a filter connected between the transmitter module and the antenna for passing a transmitted signal from the transmitter module to the antenna in the transmission mode. The filter also acts to cut off a reception frequency in the reception mode. The switching apparatus further comprises a first switching device for isolating the transmitter module and the antenna from each other in the reception mode, and a second switching device for isolating the antenna and a receiver module from each other in the transmission mode. No separate ¼ wavelength strip line is required, making the circuitry of the switching apparatus simpler and, thus, the size thereof smaller.

Abstract: A dielectric filter is disclosed in which an open area without being spread with a conductive material is formed on the rear face of a dielectric block with a conductive material spread thereon, thereby making it possible to improve the filtering characteristics of the filter and to miniaturize the filter. That is, coupling capacitances and coupling inductances are formed between resonance holes of the rear face of the dielectric block. Further, conductor patterns are formed on the front face of the dielectric block so that coupling capacitances are formed between the resonance holes of the front face, and that loading capacitances are provided to the respective resonance holes.
