Implementation of a Power Combining Network for a 2.45 GHz Transmitter Combining LINC and EER

F. Wang, O. Koch


A power combining network with 180N hybrid for a 2.45 GHz Transmitter Combining LINC and EER has been analyzed, built and measured. The network feeds the wasted outphasing power partly back to the power supply and therefore improves the overall power efficiency. The recycling circuit was designed and simulated with ADS. A measured peak recycling efficiency of 60% was achieved with commercial Schottky diodes at 2.45 GHz at an input power of 36 dBm.
