Abstract

The invention discloses an SCM standing-wave ratio monitoring circuit applied to a power amplifier. The SCM standing-wave ratio monitoring circuit comprises a standing-wave ratio monitoring circuit and an SCM circuit which are connected with each other, wherein the standing-wave ratio monitoring circuit comprises a power amplifier final stage tube, a micro-strip circuit, a forward detection circuit, a reverse detection circuit, a comparison operational amplifier and an RF isolator; one end of the micro-strip circuit is connected with the power amplifier final stage tube, and the other end is connected with the forward detection circuit; one end of the RF isolator is connected with the power amplifier final stage tube, and the other end is connected with the reverse detection circuit; and the forward detection circuit and the reverse detection circuit are connected with the comparison operational amplifier separately. The SCM standing-wave ratio monitoring circuit applied to the power amplifier disclosed by the invention achieves the precise coupling of RF signals, feedback signals are transmitted reliably through a detection tube-to-voltage mode, and the maintenance achieves intelligent locking of frequency; and the SCM standing-wave ratio monitoring circuit can operate online, and has the advantages of high output frequency, good suppression and good product stability.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a single-chip standing wave ratio monitoring circuit applied to power amplifiers. Background technique [0002] Currently, considering the looming global energy crisis and increasing expectations for environmental protection, energy saving is crucial for the operation of efficient wireless networks. Power amplifiers (PAs) are at the heart of base stations and repeaters, and their power consumption can account for half of the total power consumption of a base station. Monitoring the power amplifier can not only improve power efficiency, reduce operating costs, improve output power and linearity, but also enable system operators to discover and solve problems in a timely manner, thereby improving reliability and maintainability. The ratio monitoring can intelligently monitor the working status of the power amplifier in real time to ensure the normal operation of the wireless n...
