Abstract

The invention discloses a microwave amplitude regulator for solving the problem of high stability, high accuracy and ultra-wideband output of microwave signals. The microwave amplitude adjuster comprises a first gain control unit, a first power amplifier, a first coupler and a first programmed attenuator, the first gain control unit is used for performing automatic gain control on an input first microwave signal to obtain a first gain signal, and outputting the first gain signal to the first power amplifier; the first power amplifier is used for performing power amplification on the received first gain signal to obtain a first high frequency signal, and outputting the first high frequency signal to the first coupler; the first coupler is used for coupling the received first high frequencysignal to obtain a first coupling signal and outputting the first coupling signal to the first programmed attenuator; and the first programmed attenuator is used for performing programmed power attenuation, receiving the first coupling signal and outputting a first radio frequency signal. The microwave amplitude regulator has the advantages of high stability, high accuracy and ultra-wideband of the output microwave signal.

Description

technical field [0001] The invention belongs to the technical field of communication, in particular to an ultra-wideband and high-speed microwave signal amplitude regulator. Background technique [0002] In the microwave frequency synthesis technology, it is often required to achieve high stability, high precision, and small-step regulation of the microwave output signal power amplitude. Unable to achieve. Therefore, in order to achieve high stability, high precision, and small-step control requirements for the power amplitude of the microwave output signal, it is often necessary to process the microwave output signal through an amplitude regulator at the final stage of the frequency synthesizer, so that when the input signal is within a wide range When changing, the amplitude of the output signal remains constant, that is to say, when the power of the input signal is unstable, after amplitude control, the power of the output signal is stabilized at a relatively constant am...
