Abstract
An automobile remote control circuitry. There are wireless transmission circuitry and wireless receiving circuitry each on the remote control itself and the circuitry inside the automobile. The special feature: the wireless transmission circuitry and wireless receiving circuitry apply the same specification of LO base band frequency circuitry. Based on above structure, it can reduce the number of components used in the bi-direction remote control, lower the total component cost and easier in manufacture processes.
