Negative-resistance diode power amplification

Abstract

An analysis is presented for the nonlinear behavior of power amplifiers utilizing negative-resistance diodes in a reflection circuit. The analysis applies to both stable and locked-oscillator modes of operation. Special emphasis is given to a simple model involving a cubic nonlinearity in the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">I-V</tex> relationship, and to the idealized LSA device in an amplification mode.
