Abstract

The invention discloses a satellite measurement and control transmitter with variable frequency points. The satellite measurement and control transmitter comprises a first filter, a variable local oscillator module, a frequency mixer, a first amplifier, a second filter, a second amplifier, a third filter, a power amplifier, a coupler, a detector, an operational amplifier and an isolator. The satellite measurement and control transmitter for the UHF frequency band can work on a variable working frequency point of the UHF frequency band, input fixed intermediate frequency transmitting signals and variable local oscillation signals are subjected to frequency mixing, power amplification is carried out on the UHF frequency band, and high-power signal transmitting of the variable working frequency point is achieved.

Description

technical field [0001] The invention relates to the technical field of satellite measurement and control communication transmitters, in particular to a variable frequency point satellite measurement and control transmitter. Background technique [0002] In the application of satellites, Mars exploration, Chang'e lunar exploration and other aerospace projects, the spacecraft measurement and control communication system undertakes communication functions such as telemetry, remote control, tracking, ranging, and speed measurement of the spacecraft. Measurement and control communication tasks usually refer to the reception and transmission of remote control and telemetry data between spacecraft and ground stations, or between spacecraft and spacecraft. The spaceborne measurement and control equipment equipped on the spacecraft is composed of a receiver and a transmitter to jointly complete the above communication tasks. [0003] Due to the limitation of design technology, the c...
