Design of RF Frontend Unit to Avoid Intermodulation Using Arduino Uno

Abstract

Designing a Radio Frequency (RF) front end is vastly realized for determining the level of integration that is required in the signal chain inside the receivers to be idealistic. The receivers is susceptible to harmful intermodulation due to nonlinear RF front ends. In this paper, intermodulation distortion is avoided by a selective prototype hardware design of RF fort end which is connected with the Arduino Uno for controlling the power levels. The measurements are tested out as a result of injecting a signals within x-band frequencies and chosen different power levels are assumed. These measurements is revealed an accepted results for the intermodulation avoidance.
