Title MILLIMETER WAVELENGTH RANGE WIRELESS TRANSCEIVER DEVICE
Abstract

Provided is a millimeter wavelength range transceiver device which can improve phase noise characteristics and which can also independently calibrate each respective local oscillator of a transmission unit and a reception unit. This millimeter wavelength range transceiver device comprises a transmission unit (10), a reception unit (20), and a reference frequency signal generator (30). The transmission unit (10) comprises a transmission-use local oscillator (11) comprising an injection-locked oscillator, a transmission-use mixer (12) for mixing the signal from the transmission-use local oscillator and a transmission baseband signal, and a transmission-use amplifier (13) for amplifying the signal from the transmission-use mixer to a transmission-use antenna (15). The reception unit (20) comprises a reception-use amplifier (25) for amplifying a signal from a reception-use antenna (24), a reception-use local oscillator (22) comprising an injection-locked oscillator, and a reception-use mixer (23) for mixing the signal from the reception-use local oscillator and the signal from the reception-use amplifier in order to output a reception baseband signal. A reference frequency signal generator (30) injects a reference frequency signal into the transmission-and-reception-use local oscillators (11 and 22).
