Abstract

The invention discloses a radio frequency matrix testing apparatus of a radio frequency power amplifier, promising to provide a radio frequency testing matrix that has strong universality, low cost and simple design. According to the technical solution of the invention, the apparatus involves: a radio frequency testing matrix is provided therein with one 2in1 switch which switches a communication signal source and a vector network, a ring switch 1 and a ring switch 2 which switches a communication 9in1 switch. Two ring switches in series connection simultaneously select a directly connected path. Each ring switch is provided with an A signal input port, a C signal input port, a D signal input port, and a B signal input port. A signal input port B of the ring switch 2 is in switched connection to a multi-signal output port through the 9in1 switch. A signal input port A of the ring switch 1 is in parallel connection to the 2in1 switch through a radio frequency power amplifier. The apparatus receives signals from a signal source and the vector network, transmits the signal from the signal input port, to the signal input port B to a signal input port A of the ring switch 2, and transmits via the signal input port B of the ring switch to the 9in1 switch.

Description

technical field [0001] The invention relates to a universal radio frequency matrix suitable for automatic testing of radio frequency power amplifiers, which is general hardware for automatic testing of radio frequency power amplifier indicators. Background technique [0002] The power amplifier that sends signals to the transmitting antenna is often a key device that affects the performance of the entire transmitting system. As the core component of the transmitter, the RF power amplifier's performance is a key factor that restricts the performance and technical level of the entire system. The demand for power amplifiers in the entire communication field is huge, and the quality requirements are also extremely high. Especially in the field of military communication, the quality of the power amplifier determines the success or failure of the entire communication system. The power amplifier consumes nearly 80% of the electric power of the wireless communication system, and t...
