摘要
By ensuring that the subject innovation is transmitted and received by performing a half-duplex two-way radio transceiver mixer and band-pass filter is an amplitude shift keying function and frequency conversion function provided in the transmission path from the performed in turn alternately by time-sharing manner, the transmission and reception path is compared to the provided independently of the wireless communication transmitting and receiving apparatus in which the transmission and reception path set by the mixer and band-pass filter which can be easily and enhance the competitiveness to the circuit configuration.; To this end, the subject innovation is a half-duplex two-way radio communication send and receive unit is provided with transmitting and receiving data separator for separating the received data signal supplied from the transmission data with the antenna in the authorized from the transmitting and receiving data separator the transmitted data and a high-frequency local oscillation isolated by by mixing a local oscillation signal shifted amplitude for the transmitted data for transmitting subjected to modulation in the following transmission path the other hand converts the received data input from the antenna into an intermediate frequency signal with the local oscillator signals and the converted via a receive path connected to the mixer and the mixer passes the IF signal, and the wireless communication transceiver band-pass filter for removing limiting the band of the transmission data or unnecessary signals included in the received data is provided to the transmission and reception common path is provided .
