Abstract :
Experiments have been carried out to determine the AM-PM conversion coefficients of traveling-wave tubes, tunnel diode amplifiers, and parametric amplifiers. Phase-input power characteristics have been measured by a precision phase bridge, and formulas are quoted for the calculation of both intelligible and unintelligible cross-talk coupling when the device handles multiple FM carriers.
