Abstract： A 2.4 GHz six channels model aircraft wireless transceiver system was designed based on the wireless transceiver chip A7105 and the single chip WT51F516.The core modules of this wireless transceiver system were radio frequency chip A7105 and power amplifier chip AP1110,and frequency hopping mechanism was applied for data transmission.50 Ω Impedance matching circuits were obtained by analyzing impedance characteristics of peripheral circuit of radio frequency chip A7105 and antenna based on ADS software.The system was successfully realized the transmitting and received wireless signals within 100 meters.The system has the characteristics of low cost,small power consumption and far receiving distance.This could be applied in low-end model aircraft.
