To provide a transmission and reception module for eliminating a deterioration in a noise index that occurs in a receiving system by protecting the receiving system from excessive reflection power from an antenna.

The transmission and reception module is provided with a distributing part 2 for distributing a high-frequency signal to a plurality of high-frequency signals; power amplifying parts 3 and 4 for amplifying the respective high-frequency signals; a compositing part 5 for compositing the respective high-frequency signals; two first circulators 6 and 7 having terminals 6a and 7a connected to the power amplifying parts 3 and 4, terminals 6b and 7b connected to the compositing part 5, and terminals 6c and 7c connected to terminators 11 and 12 and provided according to the power amplifying parts 3 and 4; a second circulator 8, having a terminal 8a connected to the compositing part 5, a terminal 8b and a terminal 8c connected to an antenna terminal 9; and a received signal amplifying part 10, connected to the terminal 8c to amplify a signal outputted from the terminal 8c, wherein a high-frequency wave signal reflected at the received signal amplifying part 10 is absorbed by the terminators 11 and 12.
