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 (), a reception unit (), and a reference frequency signal generator (). The transmission unit () comprises a transmission-use local oscillator () comprising an injection-locked oscillator, a transmission-use mixer () for mixing the signal from the transmission-use local oscillator and a transmission baseband signal, and a transmission-use amplifier () for amplifying the signal from the transmission-use mixer to a transmission-use antenna (). The reception unit () comprises a reception-use amplifier () for amplifying a signal from a reception-use antenna (), a reception-use local oscillator () comprising an injection-locked oscillator, and a reception-use mixer () 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 () injects a reference frequency signal into the transmission-and-reception-use local oscillators (and).
