Simplified calculations on some common passive microwave networks

Calculating the required line impedances for a specified performance on passive microwave networks like directional couplers and power dividers/combiners is a well-known problem. A simple method is presented that uses the net power flow in the transmission lines of the network, together with power conservation at the intersections. © 2001 John Wiley & Sons, Inc.
