Abstract: A radio frequency (RF) power divider/combiner circuit prevents an unbalance in current consumption according to a variation of the load, and reduces size of a power amplifier when employed therein. In an exemplary embodiment, the RF power divider/combiner circuit includes an input terminal, first and second output terminals, a first microstrip line connected to the input terminal and a second microstrip line vertically connected to the first microstrip line. A first capacitor is connected between a middle of the second microstrip line and ground. A first inductor has a first end connected to an end of the second microstrip line, a second inductor has an end connected to another end of the second microstrip line, and a second capacitor is connected between a second end of the first inductor and a second end of the second inductor.
