Broadband signal generator

Abstract

The invention provides a broadband signal generator. The broadband signal generator is characterized by comprising a communication control module, an intermediate frequency processing module, an up and down frequency conversion module and a local oscillator module. The intermediate frequency processing module modulates various modes of modulating signals into central frequency and sends the signals to the first frequency conversion branch and the second frequency conversion branch, and then the signals are output at two frequency bands of 30-560 MHz and 560-1000 MHz after being frequency-converted twice by the local oscillator module. The broadband signal generator overcomes the problems of poor frequency accuracy, narrow frequency range, low reaction speed, less function and the like in the prior art and meanwhile improves the production efficiency and facilitates batch production.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a broadband signal generator. Background technique [0002] In wireless communication systems, signal generators with high precision, high resolution, and wide frequency range are widely used.
