Abstract :
Surface acoustic wave filters have not, for a number of reasons, become widely used in mobile radio equipment to date. A brief resume of the historical development of receiver architecture is presented and the design of two receiver systems is described in which the properties of surface acoustic wave filters are used to best advantage: a double conversion superheterodyne portable radio telephone receiver and a synchrodyne paging receiver. The use of surface acoustic wave filters in these receiver systems is seen to offer advantages with regard to size and power consumption.
