Abstract :
A non-uniform 2D propagation medium is compatible with modern IC processes and is used to produce a 4-to-1 broadband power combiner called an electrical funnel. The combiner is used in a wideband power amplifier in a 0.13mum SiGe BiCMOS process and yields 125mW peak output power at 85GHz with a 24GHz 3dB bandwidth
