Title: Kalman Kaufman: Innovator in Radio-Frequency Amplification

Introduction

Kalman Kaufman is a notable inventor based in Ramat Hasharon, Israel. He has made significant contributions to the field of radio-frequency technology, particularly through his innovative patent in power amplification.

Latest Patents

Kaufman's most recent patent is for a super-linear multi-carrier power amplifier. This invention involves a super-linear feedforward amplifier designed to amplify radio-frequency input signals produced in one or more frequency channels over an input band. The amplifier includes a radio-frequency power amplifier that enhances the signals. A signal cancellation circuit loop generates an error signal that responds to distortion products in the amplified signals. Additionally, a digital correction block equalizes the input signals based on the amplifier's transfer function, effectively canceling the input signals from the error signal across the entire input band. An error cancellation circuit loop then subtracts the error signal from the amplified signals to produce a linearized output signal.
