Abstract
A communication module is provided in which its characteristic of separation between its first and second tuner units is improved. The module is equipped with a circuit board having a first main surface, and a second main surface opposite to the first main surface; a first amplifier arranged on the first main surface, for amplifying a first signal; a first mixer arranged on the first main surface, for converting a signal supplied from the first amplifier to an intermediate-frequency signal; a second amplifier for amplifying a second signal; and a mixer for converting a signal supplied from the second amplifier to an intermediate-frequency signal, both arranged on the second main surface of the circuit board.
