The Volterra Input-Output Map of a High Frequency Amplifier as a Practical Alternative to Load-Pull Measurements
نویسندگان
چکیده
Using a nonlinear black-box model based on the Volterra theory it is possible to describe the nonlinear behavior of a high frequency amplifier. Acquiring only a strongly reduced set of measurements it is easy to predict the load impedance curves anywhere on a Smith Chart. The classic load-pull approach involves the acquisition of a large amount of data and still lacks a description of the nonlinear behavior of the amplifier in deviating situations.

This article proposed a simple self cascode RGC amplifier configuration to increase the gain and bandwidth. The cascode amplifier eliminates the miller capacitance between input and output and facilitates high gain, high input and output impedance with high bandwidth. However, the cascode amplifier requires relatively high supply voltage for proper operation and it decreases the output voltage ...

A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...
