Problems solved by technology

[0007] Using radio frequency connectors to separate and connect radio frequency small signals or intermediate frequency signals is a relatively common way of dividing boards. However, the inventors of the present invention have found that the cost of dividing boards is relatively high by using radio frequency connectors. At the same time, the loss caused by the RF connector is also large

Embodiment Construction

[0027] The embodiment of the present invention provides a transceiver device and a radio frequency remote module, through the digital connector between the intermediate frequency processor and the conversion module to achieve board splitting, because the digital connector transmits the digital signal, and the digital signal is transmitted There is almost no loss in the process, thereby eliminating the loss caused by split boards.

[0028] like Figure 2a As shown, the transceiver device provided by the embodiment of the present invention includes:

[0029] The analog transceiver 201 is used to perform demodulation processing and analog-to-digital conversion on the received signal after receiving the uplink signal, and perform digital-to-analog conversion and modulation on the received downlink signal after receiving the downlink signal Process and send the converted downlink signal;

[0030] The digital intermediate frequency processing unit 202 is used to process the digita...

Abstract

The invention discloses a transceiver device and a radio frequency far-end module, which relate to the communication technology. The embodiment of the invention realizes the board split between an intermediate frequency processor and a conversion module through a digital connector, since the digital connector is used for transmitting a digital signal, the digital signal almost has no consumption during the transmitting process, and thus the consumption caused by the board split is removed.

Description

technical field [0001] The invention relates to communication technology, in particular to a transceiver device and a radio frequency remote module. Background technique [0002] At present, in the architecture design of a radio remote unit (RRU, Radio Remote Unit) of a base station, the transceiver often uses a sub-board technology. [0003] A typical RRU transceiver architecture such as figure 1 As shown, it includes an analog transceiver part 101, and a digital intermediate frequency and digital system management part 102, wherein: [0004] The analog transceiver part 101 includes conventional processing devices such as power amplifier, low noise amplifier, modem, filter, analog-to-digital conversion (ADC), digital-to-analog conversion (DAC), and can use radio frequency and intermediate frequency gain-adjustable amplifiers for gain compensation ; [0005] The sub-board can be set between the radio frequency and the intermediate frequency, and the reliable and performan...
