Abstract

A dynamically tuned repeater system for improved communication system performance is disclosed. The repeater circuit consists of power amplifiers, low noise amplifiers, filters, switches and antennas along with tuning circuits integrated and controlled to provide an optimized system for RF transmission improvement. Dynamic tuning provides the ability to maintain optimized system performance as required by communication link characteristics. Inputs from proximity sensors are used to further optimize system performance. The repeater topology is capable of transmission and reception enhancement at a multitude of frequency bands.
