PROBLEM TO BE SOLVED: To provide a harmonic control circuit which is compact and less in transmission loss, and by which the power utilization efficiency of a high frequency power amplifier is enhanced. SOLUTION: The high frequency power amplifier includes an amplification element 204, a harmonic control circuit 209, an output matching circuit 207 and a load resistor 208. A high frequency signal inputted from an input end 201 is amplified in the amplification element 204, passes through the harmonic control circuit 209 and the output matching circuit 207, and is then supplied to the load resistor 208. The harmonic control circuit 209 includes a first dielectric resonator 206 and a second dielectric resonator 205. COPYRIGHT: (C)2009,JPO&INPIT
