High frequency module and receiver

摘要

There are provided a high frequency module and a receiver capable of exhausting an electric field and a magnetic field to the outside of a shield, more closely arranging electronic components inside the shield, and being downsized. The high frequency module has integrated circuits (IC) 112, 113 each incorporating an oscillator including an inductor, and a shield case 114 as a shield for covering the ICs 112, 113, and the shield case 114 as a shield is formed with openings 116A, 116B having a size equal to or more than half the shape size of the ICs 112, 113 in areas opposed to the arrangement positions of the ICs 112, 113.

主权项

1. A receiver comprising:
an input terminal to which a satellite broadcast signal or a terrestrial broadcast signal is input; a satellite broadcast receiving circuit including a satellite tuner having a function of frequency-converting the satellite broadcast signal; a terrestrial broadcast receiving circuit including a terrestrial tuner having a function of frequency-converting the terrestrial broadcast signal; and a branching circuit for putting the satellite broadcast signal input from the input terminal into the satellite broadcast receiving circuit and putting the terrestrial broadcast signal into the terrestrial broadcast receiving circuit, wherein the satellite tuner and the terrestrial tuner are formed as a satellite tuner integrated circuit and a terrestrial tuner integrated circuit each incorporating an oscillator, respectively, and include a shield for covering at least the satellite tuner integrated circuit and the terrestrial tuner integrated circuit, and the shield is formed with an opening having a size equal to or more than half the shape size of the integrated circuit in an area opposed to the arrangement position of at least one integrated circuit among the satellite tuner integrated circuit and the terrestrial tuner integrated circuit.
