【Abstract】 This thesis introduces the fundamental functions and characteristics of SA605, a chip for communications uses produced by Philips Semiconductors. Based upon SA605 and DDS technology which is now developing fast, a practical scheme of RF signal re-ceiving system is designed. The scheme can be applied in the receiving unit of a space signal tester. Some problems in the circuits’ realization are expounded and the corresponding solutions have been given.更多还原
