Abstract :
The use of P.L.L. frequency synthesis in transceivers for Land Mobile use is growing rapidly. This paper considers some of the problems of the design of such synthesisers and some solutions to them. The topics covered are the use of surface acoustic wave devices in stable V.C.O.s, the design of type II phase/ frequency comparators, and the design of programmable dividers for operation at V.H.F. and U.H.F. Frequencies.
