A Comprehensive Test Approach on High-Power Low-Noise Intermodulation Distortion

Effect of Low Frequency Memory on High Power 12W LDMOS Transistors Intermodulation Distortion

The increasing demand for higher data rates in wireless communication systems has led to the more effective and efficient use of all allocated frequency bands. In order to use the whole bandwidth at maximum efficiency, one needs to have RF power amplifiers with a higher linear level and memory-less performance. This is considered to be a major challenge to circuit designers. In this thesis the ...

CHARACTERIZING IMD Characterizing Intermodulation Distortion of High - Power Devices

Modern wireless communication systems demand for high power and broadband devices. There are different technologies emerging offering more and more power density, with single devices delivering power levels above 100 watts. These devices are targeted for broadband telecommunications like W-CDMA or Wi-Fi application. Intermodulation distortion is very critical in these applications because it ge...

Analog Filter Banks with Low Intermodulation Distortion

It is demonstrated that the filter-bank structure of [1] can be designed to significantly reduce the effect of intermodulation distortion. This gives it an important advantage over other structures in radio systems. The principle is explained, and supported with Volterra analysis and simulation.

Intermodulation Distortion

On Cuba , Diplomats , Ultrasound , and Intermodulation Distortion

This technical report analyzes how ultrasound could have led to the AP news recordings of metallic sounds reportedly heard by diplomats in Cuba. Beginning with screen shots of the acoustic spectral plots from the AP news, we reverse engineered ultrasonic signals that could lead to those outcomes as a result of intermodulation distortion and non-linearities of the acoustic transmission medium. W...
