摘要： A high-frequency module includes a switching circuit having a phase-shift circuit. The phase-shift circuit matches only PCS/DCS reception signals so as to be passed therethrough by setting a control-voltage input terminal to a Low level when receiving PCS/DCS signals, and attenuates PCS/DCS transmission signals to the PCS/DCS reception circuit side by setting the control-voltage input terminal to a Hi level when transmitting PCS/DCS signals. Also, another phase-shift circuit, which further attenuates the PCS transmission signal when transmitting the PCS signal, is provided in the DCS Rx terminal side of the phase-shift circuit.

摘要： In a filter module, a common input/output portion of a switch circuit is set as a first port. A first filter arranged to pass a signal in a first frequency band is connected between a first input/output portion of the switch circuit and a second port. A second filter arranged to pass a signal in a second frequency band is connected between a second input/output portion and the second port. A phase adjusting circuit is provided such that an impedance in the second frequency band as seen from the first port while the switch circuit selects the first input/output portion is in a substantially short-circuited state. This arrangement prevents leakage of unwanted signals from a signal path used in a communication system not in operation among two communication systems for different frequency bands while the other communication system is engaged in communication.

A first variable capacitance element and a first fixed capacitance element are connected in series, and the series circuit thereof and a second fixed capacitance element are connected in parallel. Accordingly, with reference to the capacitance of the second fixed capacitance element, the range of the combined capacitance of the variable capacitance circuit is provided by a step size of capacitance based on the combined capacitance of the variable capacitance element and the first fixed capacitance element. The first and second fixed capacitance elements are defined by inner-layer flat-plate electrodes in a laminated substrate, and the variable capacitance element is defined by an MEMS element mounted on a top surface of the laminated substrate.
