Abstract
Afrequency source with output frequency of 6 MHz was designed for 406 MHz rescue beacon. In the design,a singlechip positioning data receive and Manchester encoding were achieved by the aid of SCM technology. BPSK modulation and frequency synthesis of carrier wave realized with DDS chip AD9852. The circuits of hardware interfaces from to GPS chip and from singlechip microcomputer to AD9852,as well as the codec program and design of the elliptic filter were researched em-phatically.关键词
