Abstract

A power supply circuit for miniaturizing an ODU transmit channel is disclosed, comprises a 5V voltage input terminal and a 6V voltage input terminal, The 5V voltage input terminal passes through a first power filter network to obtain a voltage stabilization 5V, and is divided into a plurality of independent power supply branches to supply power to a plurality of chips of the emission channel respectively. The 6V voltage input terminal passes through a second power filter network to obtain a voltage stabilization 6V, and supplies power to a radio frequency power amplifier in the emission channel. The power supply circuit further includes a protection circuit for supplying power to the power amplifier. The power supply circuit can provide an independent power supply branch for a plurality ofchips in a transmitting channel, so that the chips with radio frequency characteristics do not generate mutual interference of power supply, the electromagnetic compatibility is enhanced, the power supply protection of the power amplifier can be carried out, and the reliability and the stability of the work are enhanced.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a power supply circuit suitable for a miniaturized ODU transmission channel. Background technique [0002] In satellite communication equipment, ODU (Out-door Unit) refers to the outdoor unit, mainly including frequency conversion and power amplification, which can be divided into transmission channel and reception channel. The transmission channel usually refers to BUC (Block Up-Converter), That is, the up-conversion power amplifier, and the receiving channel mainly refers to LNB (Low Noise Block down-converter), that is, low noise amplifier and frequency converter. [0003] In the transmission channel, the power supply circuit is usually required to provide DC power for each active radio frequency device in the transmission channel, but when the same DC power supply output supplies power to multiple radio frequency devices, it is easy to cause these radio freq...
