WIDE DYNAMIC RANGE VHF PRESELECTOR.
Abstract
Simultaneous operation of a transmitter and receiving device in close proximity to each other results in receiver desensitization and distortion due to cross-modulation effects. Utilization of parametric conversion techniques now provides the design engineer with a frequency converter which is considerably more amplitude-linear than conventional devices, with the added features of low noise characteristics and wide dynamic range capability. This report presents a development concerning the design and performance of a tunable parametric preselector operable over the range of 30-70 MHz. Also presented is a discussion of the ramifications of selecting the specific circuitry and parts. (Author)
