研究目的
To demonstrate the use of a 5.8 GHz injection-locked magnetron for transmitting digital data via frequency shift keying (FSK) modulation, aiming to control motors wirelessly and explore future applications in wireless power and data transfer systems.
研究成果
The study successfully demonstrated that a 5.8 GHz injection-locked magnetron can transmit motor control data via FSK modulation without bit errors, paving the way for future wireless power and data transfer systems.
研究不足
The FSK bandwidth must be narrower than the magnetron's locking range to maintain locking status. Increasing injection power can allow faster data transmission rates.
1：Experimental Design and Method Selection:
The study utilized a 5.8 GHz injection-locked magnetron for FSK modulation to transmit data. A LabVIEW program controlled the modulator, which modulated the control signal on the microwave by FSK. The modulated signal was amplified and injected into the magnetron, which then amplified and transmitted the signal. At the receiver, the signal was demodulated to control motors.

Sample Selection and Data Sources:
2. Sample Selection and Data Sources: The experiment involved modulating a motor control signal and transmitting it via the magnetron. The received signal was demodulated to verify data integrity and control motors.
3：List of Experimental Equipment and Materials:
Equipment included a LabVIEW program, Pakite PAT-630 transmitter and receiver, a 5.8 GHz magnetron, a circulator, antennas, and a driver circuit for motor control.
4：8 GHz magnetron, a circulator, antennas, and a driver circuit for motor control.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The process involved modulating the control signal, injecting it into the magnetron, transmitting the modulated microwaves, receiving and demodulating the signal, and using the demodulated data to control motors.
5：Data Analysis Methods:
The demodulated data was checked for errors by feeding it back to the PC, confirming no bit errors in transmitted data files larger than 1 MB.
