摘要:
A technique capable of promoting miniaturization of an RF power module used in a mobile phone etc. is provided. A directional coupler is formed inside a semiconductor chip in which an amplification part of the RF power module is formed. A sub-line of the directional coupler is formed in the same layer as a drain wire coupled to the drain region of an LDMOSFET, which will serve as the amplification part of the semiconductor chip. Due to this, the predetermined drain wire is used as a main line and the directional coupler is configured by a sub-line arranged in parallel to the main line via an insulating film, together with the main line.

An attenuating antenna switch may be used to suppress increase in the scale and power consumption of an RFIC. The antenna switch has a first terminal, a second terminal, and an antenna terminal coupled to the first and second terminals and configured to be connected to an antenna. The first switch switches between a first state in which a high frequency signal is propagated between the first terminal and the antenna terminal, and a second state in which the high frequency signal is interrupted. A second switch switches between the first and second states between the second terminal and the antenna terminal. The first and second switches are controlled in a mutually exclusive manner such that only one of the two switches can be in the first state at any given time. When in the first state, each switch adjusts an attenuation amount of the high frequency signal.

The plug shell of the electrical connector includes the accommodation portion for accommodating the contact pin and the housing that holds the contact pin, the insertion port for inserting the contact pin and the housing into the accommodation portion, the lid member for closing the insertion port, and the hold mechanism for holding the lid member. The hold mechanism includes the pedestal, on which the lid member is placed, and the pair of hold pieces, which hold the lid member on the pedestal by pressing. The pair of hold pieces press the end portions of the lid member toward the pedestal, so that thereby a stress that urges the end portions to become distant from the pedestal is generated in the lid member.
