Abstract
The invention provides a power sharing amplifier system for a cellular communications system, having with an 8th order transform matrix circuit, eight power sharing amplifiers and an 8th order inverse transform matrix circuit. The 8th order transform matrix circuit has six input ports and responds to six RF input signals for providing 8th order transform matrix RF input signals. The 8th order transform matrix circuit also has two input ports that do not receive input signals, but instead are coupled through a resistor to ground. The eight power sharing amplifiers respond to the 8th order transform matrix RF input signals, for providing eight amplified transformed RF signals. The 8th order inverse transform matrix circuit responds to the eight amplified transformed RF signals, for providing six inverse transform amplified RF output signals to six output ports. The 8th order inverse transform matrix circuit also has two output ports that do not provide output signals to an antenna, but instead are coupled through a resistor to ground for dissipating intermodulation distortion products.
