SINGLE-BAND SHF MODULATOR AS THE LOCAL OSCILLATOR IN A EPR SPECTROMETER.

Abstract

A single-band crystal diode modulator using a slotted bridge is described in which, as a result of combined amplitude and phase modulation of SHF diode oscillations, a single-band signal power of 0.5-0.6 mw is obtained when 5-7 mw are shunted into the modulator canal. The carrier and second side frequency are suppressed not less than 50-55 db. Suppression of the higher side frequencies is no worse than 30-35 db. The described modulator is of extremely simple design and may be made very compact. The device is successfully used in place of the local oscillator in a radiospectrometer for analysis of electron-nuclear double resonance. (Author)
