1. Introduction a. Four RC cars can be played in dividually in same frequency band b. Using Timing sharing for data transmission c. Using 4 different ID to distinguish from 4 different RC cars d. 4 functions including forwar d, backward, left and right e. This device complies with part 15 of the FCC rules, Operation is subject the following two conditions: 1) This device may not cause harmful interference and. 2) This device must accept any interference received including interference that may cause undesired operation 2. TX (49MHz) TX is supplied by a 9V battery and regulate 5V 1 to the IC GPRC11A-005C. There is a four position selector SW1 to select different ID for the TX. In the TX, there are four function keys S1, S2, S3,S4,S5 & S6 to control the RC car (left, right, backward, forward1, forward2 & forward3). The modulating signal from IOC1 of GPRC11A-005C will be modulated by carrier frequency 49.86MHz. The modulated signal will be amplified and pass through Q2 & matching network to antenna. The matching netw ork consists of L3, C14,C15 & L4.
