| Abstract: | The paper introduces a wireless spread spectrum industry controller system based on SC1128, which uses AT89S52 as the control center circuit and the RF Wireless Transceiver circuit composed by spread spectrum IC SC1128, MC13156 and PLL IC LMX2315. Meanwhile, this system makes many communication channels changing come true. The receiver part adopts super heterodyne system and the transmitter part exerts direct Variable Capacitance Diode modulation. Integrate circuits are adopted in both receiver and transmitter subsystems, which make this design simple and credible. |
