Abstract

The invention discloses an ultra-fast ultra-bandwidth low-noise band agile frequency source which is composed of a shell and a synthetic frequency module. A Control/Power interface, an REFOUT interface, an REFIN interface and an RFOUT interface are arranged outside the synthesis frequency module, wherein the Control/Power interface is numbered XS1 and is used for a power supply and a control interface; the REFOUT interface is numbered XS2 and is used for referring to a signal output interface; the REFIN interface is numbered XS3 and is used for synchronizing a signal input interface; and the RFOUT interface is numbered XS4 and is used for a radio frequency signal output interface. The ultra-fast ultra-bandwidth low-noise band agile frequency source has the advantages of wide working frequency band, high frequency hopping speed and low phase noise.

Description

technical field [0001] The invention relates to the technical field of frequency conversion equipment, in particular to an ultra-fast, ultra-wideband, low-noise and band-agile frequency source. Background technique [0002] Frequency is the number of periodic changes completed per unit time. It is a quantity that describes the frequency of periodic motion. It is often represented by the symbol f or ν, the unit is one-second, and the symbol is s-1. In order to commemorate the contribution of the German physicist Hertz, the unit of frequency is named Hertz, referred to as "Hertz", and the symbol is Hz. Every object has a frequency independent of amplitude determined by its own nature, called natural frequency. [0003] The concept of frequency is not only used in mechanics and acoustics, but also in electromagnetism, optics and radio technology. [0004] Frequency conversion is a method of designing filters, which converts a frequency band range to another corresponding freq...
