Abstract

The invention provides a UV wave band broadband reconfigurable transceiver, and belongs to the technical field of communication. A configurable local oscillation source module of the transceiver is electrically connected with a secondary frequency conversion transmitting module and a superheterodyne receiving module; the configurable local oscillation source module is used for generating a fixed frequency signal of f1 and frequency conversion frequency signals of f2-f3, and providing a local oscillation source for the secondary frequency conversion transmitting module and the superheterodyne receiving module; the secondary frequency conversion transmitting module is used for carrying out frequency spectrum shifting on f4 intermediate frequency signals with different bandwidths under the excitation of a local oscillation source to obtain radio frequency signals of f5-f6; the superheterodyne receiving module is used for carrying out frequency spectrum shifting on the radio frequency signals of f5-f6 under the excitation of a local oscillator source to obtain f4 intermediate frequency signals with different bandwidths; and the broadband frequency range and the configurability of different signal bandwidth modules can be realized.

Description

technical field [0001] The application belongs to the technical field of communication, and in particular relates to a UV-band broadband reconfigurable transceiver. Background technique [0002] Software radio is the development direction of current communication. Its purpose is to use software to configure hardware on a digital general hardware platform to realize the required radio functions. There are many types, difficult compatibility, and difficult expansion and upgrade. [0003] With the development of software radio technology, the demand for broadband reconfigurable transceivers as the front end of equipment for obtaining information is becoming stronger and stronger. At the same time, from the perspective of simplifying system design, it is also hoped that the broadband reconfigurable transceiver can perform unified intermediate frequency digital signal processing on the sending and receiving signals of each frequency band. However, there must be a series of tech...
