WIRELESS TRANSMITTER/RECEIVER, WIRELESS COMMUNICATION DEVICE, AND WIRELESS COMMUNICATION SYSTEM |
摘要 |
Disclosed is a wireless transmitter/receiver provided with: a local oscillator which oscillates at a predetermined local oscillator frequency; a mixer which mixes a local oscillation signal of the local oscillation frequency outputted from an output terminal of the local oscillator and a radio signal received by an antenna; a modulation circuit which modulates the local oscillator signal and generates a radio signal; and a transmission/reception switching unit which selectively switches over between a reception state in which the output terminal of the local oscillator is connected to the mixer and a transmission state in which the output terminal is connected to the antenna without passing through the mixer. |
