RF PREAMPLIFIER AND CONVERTER FOR TEST AND EVALUATION

Abstract

The AEL RF Preamplifier and Converter, ARDS Type 111-24D, is an adapter unit to be used in conjunction with presently-used VHF receivers. The unit is fixed-tuned and operates from 108 to 152 mc. It will enable the VHF receiver to be used on channels requiring 50 kc channel separation. The AEL RF Preamplifier and Converter has a highly selective RF front end which yields very low cross-modulation and high selectivity. The unit ered from 115 volts ac, 60 cycles. The basic feasibility of the unit was established and found to have satisfactory performance. All components and techniques could be made to meet low cost production standards. The limitation of a physical height of 1-3/4 in. prevented the use of large resonators with the resulting higher Q in the RF input filter.
