【Abstract】 The transmission and receiving of command and data in OPSEIS EAGLE system is completed by transceiver. Through its widespread application and multi-frequency technique data transmission rate is greatly increased. This paper introduces the operating principle and circuit of the receiving frequency syn-thetizer of SAR’s transceiver. Furthermore, the author analyses some common problems in using the fre-quency synthetizer and presents its solution.更多还原
