Abstract

The invention provides a semi-digital USB responder device based on an anti-fuse FPGA, and on the basis that the FPGA is adopted as a core processing chip, a digital VCO mode is adopted to be matched with an analog phase-locked loop to achieve carrier capture, tracking and subcarrier demodulation. The device is characterized by comprising a radio frequency channel module and a digital baseband module; dividing the device into six parts according to different functions, namely a receiving channel, a transmitting channel, a low-frequency processing module, a baseband module, a power supply module and a duplexer. The invention has the following obvious advantages: remote control subcarrier demodulation and telemetering subcarrier modulation functions can be realized, and remote control and telemetering interfaces are PCM (Pulse Code Modulation) forms; the data rate of the remote control PCM is flexible to set, and the data rate of the remote measurement PCM is adaptive; a small-sized integrated design is adopted, so that the volume power consumption is reduced; and modular design is adopted, so that the debugging difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of satellite measurement and control, in particular to a semi-digital USB transponder device based on an antifuse FPGA. Background technique [0002] As an important part of the measurement and control subsystem, the USB transponder provides a two-way radio frequency transmission channel between the satellite and the measurement and control ground station, and cooperates with the measurement and control ground station to complete tasks such as satellite tracking, remote control, and telemetry. [0003] With the rapid development of aerospace technology, the demand for miniaturization, light weight, complete functions and low power consumption is increasing. Compared with traditional USB answering machines, semi-digital USB answering machines have the following obvious advantages: [0004] 1) It can realize remote control subcarrier demodulation and telemetry subcarrier modulation functions, and the interfac...
