Title:
ELECTRONIC DEVICE, TUNER MODULE AND MODULE SUBSTRATE
Document Type and Number:
Japanese Patent JP3963094
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electronic device, a tuner module and a module substrate which can be miniaturized and thinned, have a simple structure, and can be mounted on a prescribed position.
SOLUTION: A tuner module 20 is provided with a module substrate 30 and a shield cover 40. The substrate 30 includes a first RF amplifier for amplifying a signal, a first oscillator for outputting a first oscillation signal, a first mixer for outputting a first intermediate frequency signal according to the signal and the first oscillation signal, a second oscillator for outputting a second oscillation signal, and a second mixer for outputting a second intermediate frequency signal, according to the second oscillation signal and the first intermediate frequency signal, where the principal part of a tuner, in which at least the first or second oscillation signal is set, so as to remove an image is integrated into an IC chip. The cover 40 has a metal pieces formed thereon. A principal substrate 10 is provided with a locked portion 11.
