Abstract: A communication terminal device is a glasses-type communication terminal device having an optically transmissive display mounted thereon. The communication terminal device includes first and second radio-frequency modules that perform radio-frequency signal processing and a baseband module that is connected to the first and second radio-frequency modules via communication lines so as to be communicable and that performs baseband signal processing. The first and second radio-frequency modules are selectively switched by the baseband module to perform a reception operation. When the first radio-frequency module performs the reception operation, a reception signal received by the first radio-frequency module is retransmitted from the second radio-frequency module.

Abstract: A radio frequency circuit includes a substrate, a first terminal disposed on a first principal surface of the substrate, a second terminal disposed on the first principal surface, a first-surface mounted component disposed on the first principal surface or inside the substrate, and a second-surface mounted component disposed on a second principal surface of the substrate which is opposite the first principal surface. A radio-frequency signal, which is input to the first terminal, is transmitted, for output from the second terminal, so as to make at least one round trip between the first principal surface and the second-surface mounted component, which is disposed on the second principal surface, through wiring lines disposed in the substrate.
