Title:
COMMUNICATION TRANSCEIVER
Document Type and Number:
WIPO Patent Application WO/2017/219954
Kind Code:
A1
Abstract:
The present invention relates to a communication transceiver. The communication transceiver comprises a receiving module, a sending module, a local oscillator module, and an antenna module. The local oscillator module comprises a local oscillator and a power splitter. A local oscillator signal is generated by using only one local oscillator, and the local oscillator signal is separately output to the receiving module and the sending module by using the power splitter. The antenna module receives a first radio frequency signal from a base station. The receiving module receives the first radio frequency signal from the base station and the local oscillator signal transmitted by using the power splitter, and down-converts the first radio frequency signal to an intermediate frequency signal for output. The sending module receive the local oscillator signal transmitted by using the power splitter and the intermediate frequency signal from an indoor exchange device, and up-converts the intermediate frequency signal to a second radio frequency signal. The antenna module sends the second radio frequency signal to the base station. In this way, receiving and sending of the radio frequency signal are completed. The communication transceiver replaces two different local oscillators that are originally required, to generate the local oscillator signal, so that the hardware costs are reduced; in addition, the device space is saved.
