Problems solved by technology

In addition, the connection structure between the main circuit board 120 and the sub circuit board 130 is also a factor for the entire circuit board to become larger
As a result, the miniaturization of the receiving device 103 is limited, and it is not suitable for the compact size required by mobile devices.

Abstract

A reception apparatus ( 3 ) which can realize a compact size thereof includes: a tuner circuit portion ( 5 ); a digital demodulating portion ( 6 ) that converts a signal from the tuner circuit portion into a digital signal; and a digital circuit portion ( 7 ) that converts a digital signal from the digital demodulating portion into a digital video signal and digital audio signal, and the reception apparatus is characterized by that a first sub circuit board ( 30 ) on which the digital demodulating portion is mounted and a second sub circuit board ( 40 ) on which the tuner circuit portion is mounted are stacked on a main circuit board ( 20 ) on which the digital circuit portion is mounted, in this order, via solder balls ( 50, 60 ), so that the main circuit board, the first sub circuit board, and the second sub circuit board are connected to each other via the solder balls.

Description

technical field [0001] The invention relates to a receiving module, a receiving device and a television receiver for receiving and demodulating radio frequency signals such as digital television broadcasting signals. Background technique [0002] The general structure of a conventional television receiver is shown in FIG. 10 as a block diagram. As shown in FIG. 10, the television receiver 101 includes: an antenna 102 for receiving a radio frequency signal; a receiving device 103 for performing predetermined processing on the radio frequency signal from the antenna 102 in order to generate a video signal and an audio signal; picture and sound An output device 104 for delivering pictures and sounds based on video signals and audio signals from the receiving device 103 . [0003] The receiving device 103 is equipped with: a tuning circuit part 105, which is used to convert the radio frequency signal received by the antenna 102 into an intermediate frequency signal; a digital d...
