Abstract

The invention relates to a method for increasing the testing safety of a high-power semiconductor amplifier. During noise power density testing, the method includes the steps of firstly, inputting safety input power PIN-safe from the input port of the high-power semiconductor amplifier; secondly, determining the output power POUT of the high-power semiconductor amplifier, and if the POUT is largerthan an upper limit, determining that an appropriate band-stop filter is not connected to the output port of the high-power semiconductor amplifier or no band-stop filter is connected to the output port of the high-power semiconductor amplifier. By the method, performance index testing during the testing of the high-power semiconductor amplifier, and the burning of precious testing instruments such as a vector network analyzer and a spectrometer.

Description

technical field [0001] The invention relates to the technical field of electronic device testing, in particular to a method for improving the testing safety of high-power semiconductor amplifier devices. technical background [0002] High-power semiconductor amplifiers are mainly used for power amplification of radio frequency microwave signals, and require good linearity indicators and high output power, so they are widely used. The main indicators for evaluating the performance of high-power semiconductor amplifiers are output power, parasitic modulation, gain, AM / PM variation coefficient, phase shift, group delay, noise figure, standing wave ratio, harmonics, power back-off, and noise power density etc. The required test instruments include vector network analyzers, power meters, spectrum analyzers, noise meters and noise sources. [0003] Taking the test of a high-power semiconductor amplifier with two-input and two-output channels as an example, according to the requir...
