Description

Technical field [0001] The present invention relates to the technical field of electronic measurement, in particular to a UHF amplifier module. Background technique [0002] With the continuous development of electronic measurement technology, the application range of frequency measurement is becoming wider and wider, and the frequency range of frequency measurement is also expanding. It can no longer be limited to the 100M range. An amplifier of about 1.3GHz is needed to meet the dynamic range of 10mVrms to For the frequency measurement of signals within 5Vrms, some of the existing technologies have insufficient dynamic range, low sensitivity, and large amplifier noise; using three-stage amplification, the bandwidth of the amplifier is only 1GHz, and the circuit design is relatively simple, without input limiting and automatic power The level control circuit, without control circuit, is a simple amplifier and cannot meet the measurement requirements. Summary of the invention [...

[0002] With the continuous development of electronic measurement technology, the application range of frequency measurement is becoming wider and wider, and the frequency range of frequency measurement is also expanding. It can no longer be limited to the range of 100M. An amplifier of about 1.3GHz is needed to meet the dynamic range of 10mVrms to The frequency measurement of the signal in 5Vrms, the dynamic range that has in the prior art is not wide enough, the sensitivity is low, the amplifier noise is big; Adopt 3 stages of amplification, the bandwidth of the amplifier is only 1GHz, the circuit design is relatively simple, there is no input limiter and automatic voltage Flat control circuit, without control circuit, it is a simple amplifier, which cannot meet the measurement requirements
