Patent

CA 2081628

In a power amplifying apparatus which has a high- frequency power divider and combiner and two to four parallel-operated power amplifiers, in which a change is made in the number of the parallel-operated power ampli- fiers so as to adjust output power, there are provided a power dividing circuit D1 having a transmission line Wd51 serving as an impedance transformer set in such a manner that the power loss is minimized by assigning an intermediate number 3 between 2 and 4 both of which indicate the number of divisions, and having four output terminals, and a power combining circuit S1 having a transmission line Ws51 serving as an impedance trans- former set in such a manner that the power loss is minimized by assigning the intermediate number 3 indica- tive of the number of combinations, and having four input terminals.
