Abstract

The invention relates to a 5G power amplifier testing device and method. The device comprises a vector network, a device under test (DUT), and a testing accessory, and is characterized in that the device also comprises a power amplifier integrated spread spectrum module at the output end and a power amplifier integrated spread spectrum module at the receiving end of the vector network; the power amplifier integrated spread spectrum module at the output end comprises a vector network output end spread spectrum module, a power amplifier and a double-shaped coupler which are electrically connected in sequence; the power amplifier integrated spread spectrum module at the receiving end comprises a vector network receiving end double-shaped coupler and a spread spectrum module which are electrically connected in sequence; and each double-shaped coupler is also electrically connected with the vector network through a respective down converter. The method adopts the spread spectrum module to perform index measurement after vector network spread spectrum, including power gain, power gain flatness, linear power gain, linear power flatness, 1dB gain compression output power, clutter suppression degree, input voltage standing-wave ratio, output voltage standing-wave ratio and power additional efficiency. According to the device and the method thereof, the test investment cost of the 5G power amplifier is greatly reduced, and meanwhile, the risks of prohibition and technology blocking are effectively avoided.

Description

technical field [0001] The invention relates to radio frequency microwave device testing, in particular to a 5G power amplifier testing device and a method thereof. Background technique [0002] The fifth-generation mobile (5G) communication technology is developing rapidly and vigorously under the promotion of the attention of countries all over the world. It has the characteristics of faster speed, wider bandwidth, higher reliability, lower delay, etc., and will bring revolutionary changes to the current industrial system. In order to achieve high speed, large bandwidth, high reliability and low delay, higher requirements will be put forward for related components, especially the research and development, manufacturing and testing of key components, such as: microwave amplifiers, mixers , filter, detector and radio frequency front end (RFFEM), etc. [0003] The microwave amplifier is one of the most critical components in the 5G key components, which greatly affects and ...
