HIGH EFFICIENCY POWER AMPLIFIER SYSTEM USING UNEQUAL POWER DISTRIBUTOR

摘要

A high efficiency power amplifier system using an unequal power distributor is provided to improve the average effectiveness level in signal having the big difference of the mean power and maximum power by distributing the electricity of the input signal. A miniature unequal power divider(510) is located in the input terminal of the high efficiency power amplifier system(500). A miniature unequal power combining structure(520) is located in the output terminal of the high efficiency power amplifier system. The electricity inputted to the unequal power divider is amplified BY the unit power amplifier located in the upside pathway. The electricity of being amplified is provided through the unequal power combining structure without the loss to the final output power.
