INTERFERENCE ANALYSIS OF NEW CIRCUIT COMPONENTS AND TECHNIQUES.
Abstract
The interference behavior of any solid-state device can be described by two quantities-the saturation input power (p sub s) and the third order intermodulation coefficient (K sub 3). Comparisons of the values of these two quantities in transistor amplifiers, parametric amplifiers, tunnel-diode amplifiers, a maser amplifier, and a crystal mixer show that large p sub s and small K sub 3 (both desirable) are generally compatible goals. Some exceptions to this rule are noted for the maser amplifier and devices operating at relatively high frequencies. Measu ents of gain, saturation, desensitiza tion, cross modulation, and intermodulation can be accomplished on a device using a single test setup. For a transistor oscillator, it is shown that: (1) a quantity zeta found for an os cillator, is related to the amount of harmonic distortion present, (2) harmonic content and fre quency stability can be improved at the expense of tunability, (3) low harmonic content can be obtained without significantly reducing output power. Diode detectors and varactor harmonic generators were also considered. (Author)
