Abstract
The present invention is related to a wireless transceiver with function of adjustment for frequency-band matching and the adjusting method therefor, mainly comprising a plurality of transmitting circuits, a plurality of receiving circuits, a frequency-band matching adjustment circuit, and a radio-frequency signal transceiving end. In this connection, the transmitting circuits and/or the receiving circuits are connected to the radio-frequency signal transceiving end via the frequency-band matching adjustment circuit. Impedance in the frequency-band matching adjustment circuit may be adjusted on the basis of the frequency-band of a RF signal, when (before) the RF signal is transmitted or received, such that high impedance or low impedance is presented in the frequency-band matching adjustment circuit with respect to the frequency-band of the received or transmitted RF signal. Thereby, loss of RF signal in reception or transmission is reduced.
