ABSTRACT:
A method and apparatus for power combining or dividing handles high impedance line requirements in n-way combiners (15) and dividers (10) using phase delay networks (12, 14) to transform impedances to a lower, intermediate impedance. Each impedance transformation is accomplished using a stepped impedance or tapered impedance transmission line (26). The method and apparatus provides isolation between input or output ports (11, 22 and 24, 13) in power combining or dividing circuits using an incremental phase delay network (12) of prescribed electrical phase lengths (22, 24) to provide phase cancellation. The power divider (10) and combiner (15) can be used in power amplifiers and in communication devices.
