A frequency translator which operates at the atomic hyperfine transition frequency of the hydrogen maser has been designed, constructed, and operated. This device, which operates in the uhf band at a frequency of about 1420 MHz, provides an output signal with a magnitude sufficient to be used in synthesizer or phase-locked systems. Lower frequency signals can be produced from these systems whose frequency stability is directly controlled by the hydrogen maser. Significant improvement in spectral purity can be realized through the use of this technique.
