Multi-band transceiver and multi-band radio frequency signal sending and receiving method

Abstract

The invention discloses a multi-band transceiver and multi-band radio frequency signal sending and receiving method. The method includes a transceiving antenna used for receiving an uplink multi-band radio frequency signal sent by a mobile station and transmitting a downlink multi-band radio frequency signal sent by a base station; a transceiving duplexer module used for filtering an out-of-band interference signal or spurious signal, filtering the uplink multi-band radio frequency signal received by the transceiving antenna and sending the signal to a receiver, and filtering the downlink multi-band radio frequency signal output by a transmitter and sending the signal to the transceiving antenna to be transmitted; the receiver used for dividing the multi-band radio frequency signal into multiple paths of single-band radio frequency signals to be processed after low noise power amplification is performed on the uplink multi-band radio frequency signal; and the transmitter used for merging the multiple paths of single-band signals into one path of multi-band radio frequency signal and performing power amplification, and sending the amplified downlink multi-band radio frequency signal to the transceiving duplexer module.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a multi-band transceiver and a method for sending and receiving multi-band radio frequency signals. Background technique [0002] With the development of wireless communication technology, the demand for wider spectrum is the most important factor affecting the evolution of technology, and wireless base station products are developing in the direction of broadband and multi-band. In the existing technology, such as figure 1 As shown, it is a simple combination of multiple single-band transceivers, and then multiple single-band transceivers are synthesized with a multiplexer to realize a broadband multi-band transceiver. This implementation method increases the complexity of the design of the transceiver, is large in size and high in cost, and does not meet the development requirements of miniaturized base stations. Contents of the invention [0003] In view of the complex ...
