摘要： For example, in a conventional high frequency switch used for a mobile phone and so on, high frequency distortion is caused by a diode which is turned off upon transmission. A high frequency switch includes a switch circuit for switching transmission and reception performed via a transmitting terminal and receiving terminals, said switch circuit having a diode turned off upon transmission, and a low-pass filter for suppressing high frequency distortion caused by the diode upon transmission.

Namely, the balanced dielectric filter comprises two resonators, each comprising plural strip-line resonating elements, disposed in parallel and mutually coupled electro-magnetically, and input and output terminals coupled to each resonator so as to function as a pair of balanced input terminals and a pair of balanced output terminals, wherein the two resonators are located in a ceramic dielectric to face each other and to be mirror images of each other. The resonating element is a quarter-wavelength resonating element, the end of the strip line thereof is grounded. The strip lines and coupling electrodes are arranged among ceramic layers, whereby the filter is integrated into a ceramic-multilayered structure.

摘要： A laminated dielectric filter is formed by coupling a plurality of resonators to one another by electromagnetic-field coupling. In the laminated dielectric filter, a bypass circuit formed of a series circuit including bypass capacitors and transmission lines is provided in parallel to a magnetic-field bypass coupling between non-adjacent resonators. Thus, capacitance of the bypass capacitors can be regulated without being affected by the magnetic-field bypass coupling between the non-adjacent resonators. As a result, attenuation poles outside a passband can be controlled freely.
