Abstract

The invention relates to a radio frequency channel for a small satellite measurement and transmission integrated machine and the measurement and transmission integrated machine. The radio frequency channel includes: a receiving channel, a transmitting channel and a clock circuit. The clock circuit provides a clock signal for the receiving channel and the transmitting channel, and the receiving channel Including combiner, low-noise amplifying unit, frequency conversion and gain control unit and receiving and amplifying unit, transmission channel includes signal receiving unit, high-speed RF modulator and power amplifying unit, combiner, low-noise amplifying unit, frequency conversion and gain control unit It is electrically connected with the receiving and amplifying unit in sequence, and the signal receiving unit, the high-speed radio frequency modulator and the power amplifying unit are electrically connected in sequence. The invention provides a radio frequency channel for a small satellite measurement and transmission integrated machine and the measurement and transmission integrated machine. Through the cooperation of a high-speed radio frequency modulator and a power amplifying unit, the bandwidth of the radio frequency transmission channel is improved, and the transmission power is increased, and can adapt to higher data rate requirements.

Description

technical field [0001] The invention relates to the technical field of satellite measurement and control, in particular to a radio frequency channel and an integrated measurement and transmission machine for a small satellite measurement and transmission integrated machine. Background technique [0002] Artificial satellites weighing less than 1000 kg are collectively called microsatellites. Microsatellites are a new generation of satellites with a clear purpose. Microsatellites have the characteristics of light weight, small size and low cost, and have the advantages of short launch period and high flexibility. They have a wide range of applications in communications, remote sensing, scientific and technological experiments, military and other fields. development, low power consumption, generalization, constellation networking and formation flight. [0003] Satellite measurement and control system and data transmission system are two important systems of satellite. The m...
