DEVELOPMENT OF AN X-BAND CW CROSSED-FIELD AMPLIFIER.

Abstract

A thermally improved helix coupled vane circuit (HCV) has been scaled for use over the 7 Gc to 11 Gc frequency range. Interaction impedance measurements verify the rapid increase in this parameter with decreased beta and point toward improved operation at lower frequencies. When operated in the conventional manner, a narrow band version of the circuit has operated with 20 db of net gain with a 20 watt peak drive signal but with only 8% efficiency. (Microsecond pulses were used for all tests.) The first test of a reentrant injected beam crossed-field amplifier has resulted in a substantial reduction of all power parameters. With this technique, 10 db of net gain has been measured with the extremely low peak drive signal of 25 mw. (Author)
