High-frequency radio apparatus

摘要

A high-frequency wireless communication device is provided that is capable of enlarging the range of communication by enhancing reception sensitivity while avoiding mutual interference. The device comprises an antenna filter and a direct detection type reception mechanism connected to the antenna filter. A crystal filter is used as the antenna filter. A crystal chip constituting the crystal filter and an IC chip into which the reception mechanism is integrated are housed in a single modular container to configure a high-frequency wireless module.
