report describes the design and operating characteristics of a pair of coherent frequency-hoppedpseudo-noise frequency synthesizers that produce a coherent 40 MHz bandwidth pseudo-noise waveform and which employ acoustic surface wave tapped delay lines as the signal-generating devices. A brief description is presented of the reason for the surface wave device implementation of the synthesizers. This presentation is followed by a detailed description of the synthesizer design. Then, a discussion follows of synthesizer testing and the results obtained. This testing revealed an RMS phase coherency between synthesizers within 0.31 radians of a perfect phase coherency, significantly better than the one radian RMS goal that had been set at the beginning of the project.
