ABSTRACT:
A power divider/combiner circuit is disclosed for connecting to a single port, 2N+1 multi-cell monolithic transistor chips, each chip composed of an even number of cells. A planar binary tree type transmission line structure is provided having first and second ends for connecting 2.sup.P trtansmission line ports at the first end to the single port at the second end, where N and P are each integers greater than or equal to 1, and an equal number of cells are connected to each of the 2.sup.P transmission line ports The value of P is chosen such that ##EQU1## where R is an integer greater than 1, and C is the sum total of the number of cells in the 2N+1 chips. R cells are connected to each of the 2.sup.P transmission line ports, and some cells from at least one transistor chip are connected to a transmission line port which is different from the port to which other cells from that one chip are connected.
