Integrated high-power signal source

Abstract

According to the integrated high-power signal source disclosed by the invention, two kinds of signal amplitude signals of 110 to 0dBm and 0 to 51dBm and the frequency of 30 to 512MHz can be output. According to the technical scheme, an excitation source module and a large signal processing module are electrically connected with a power supply processing and mainboard, and a master control microcomputer is connected with an interface control module, the excitation source module, the large signal processing module and a 5V power supply module through a serial port bus. The interface control module processes a command issued by the main control microcomputer and then issues the command to the power supply processing and mainboard through a bus; the excitation source module, the small signal processing module and the large signal processing module realize control of signal source signal frequency, large / small signal mode and power gear; the excitation source module, the small signal processing module and the large signal processing module return data, an output control result of a signal source is reported to the main control microcomputer through the interface control module, and output of large-power signals is achieved through a signal selection key and a transceiving key on a panel.

Description

technical field

[0001] The invention belongs to the field of radio product debugging instruments and equipment, and relates to an integrated high-power signal instrument and equipment that provides a frequency of 30-512 MHz and an output signal of -110-0dBm and 0-51dBm. In particular, it involves the power resistance assessment test of RF components such as filters, RF switches and limiters in the UV frequency band, the whole machine and sub-system; at the same time, it can be used as an integrated high-power signal source instrument and equipment used as a small-signal excitation source. Background technique

[0002] UV-band high-power RF components such as high-power RF distribution units, electronic switches, and co-located filter components are widely used in aviation and aerospace communication equipment. Such RF components often require high-reliability performance requirements such as "large input power, low loss, long life, safety and reliability". Based on this hig...
