Abstract:

Components and techniques for application in small lightweight X-Band detector-amplifier circuits were reviewed and evaluated. Specific areas of investigation included backward diode mixers starved mixer operation low noise transistorized I.F. preamplifiers an I.F. parametric amplifier tunnel-diode local oscillators a tunnel-diode self-oscillating mixer and low noise R.F. pre-amplifiers. High power diode limiters which require no control voltages were developed in waveguide and strip transmission line. Integrated mixerI.F. preamplifier assemblies with an overall noise figure of 8.0 db were realized. A compact solid-state local oscillator using a snap-off diode as a high order multiplier and providing an output power of 10 mwatts was developed. Also, a tunnel-diode self-oscillating mixer with integral I.F. pre-amplifier assembly was designed. Engineering test models of three solid-state detector-amplifier circuits were fabricated and tested. Overall noise figures ranging from 11.0 db to 8.0 db were obtained. The physical and performance characteristics of several detector-amplifier circuits were evaluated and compared and relationships between noise figure and weight and noise figure and cost were derived.
