摘要：
PROBLEM TO BE SOLVED: To provide a reversed power distributor and a reversed power combiner with a small scale that can be united and integrated into a RFIC and enhance the suppression characteristic at the outside of an operating band and to provide a high frequency communication apparatus employing them.
SOLUTION: An inductive component L1a is connected between an input port IN and an output port OUT 1, and a capacitive component C1a is connected between the input port IN and an output port OUT 2. A T-shaped circuit (C2a, C3a, R1a) is connected between the output ports OUT 1, OUT 2. A parallel resonance circuit (C4a, L4a) is connected between the input port IN and ground, and the output ports OUT 1, OUT 2 are respectively connected to ground via inductive components L2a, L3a. The inductive components L1a to L4a, and capacitive components C1a to C4a, and the resistive component R1 are set so that a received high frequency signal is distributed into two high frequency signals whose phase are shifted by about 180 degrees with each other and outputted.
