摘要： A high frequency module comprises a switch circuit connected to two antenna terminals and two diplexers connected to the switch circuit. Each of the diplexers incorporates two band-pass filters (BPFs). Each of the diplexers further incorporates a capacitor provided between one of the BPFs and a node of signal paths and another capacitor provided between the other of the BPFs and the node.

摘要： A high frequency module incorporates a layered substrate, a plurality of elements mounted on a top surface of the layered substrate, and a metallic casing that covers these elements. The plurality of elements mounted on the top surface of the layered substrate include a band-pass filter element. The band-pass filter element includes a plurality of conductor layers for band-pass filter and a plurality of dielectric layers for band-pass filter that implement a function of a band-pass filter, but does not include any conductor layer that functions as an electromagnetic shield. A conductor layer for grounding that the layered substrate includes and the casing are each opposed to the band-pass filter element, and thereby function as an electromagnetic shield for the band-pass filter element.

摘要： A multi-layer band-pass filter comprises an unbalanced input, two balanced outputs, and a band-pass filter section provided between the unbalanced input and the two balanced outputs. The band-pass filter section incorporates a plurality of resonators each of which is made up of a TEM line. The band-pass filter further comprises a multi-layer substrate used for integrating the resonators. The band-pass filter section incorporates, as the resonators, an input resonator, and a half-wave resonator for balanced output that is made up of a half-wave resonator having open-circuited ends. The unbalanced input is connected to the input resonator through a capacitor. Each of the balanced outputs is connected to the half-wave resonator through a capacitor.
