Claims19
A radio frequency amplifier circuit comprising:
- a plurality of transistors which are connected in parallel and output an amplified radio frequency signal;
- a plurality of first harmonic processing circuits which are connected to an output terminal of said transistors and connected to each other in parallel, and each of which processes one of an even harmonic and an odd harmonic included in the radio frequency signal;
- and
- a plurality of second harmonic processing circuits which are connected to said output terminal of said transistors and connected to each other in parallel, and each of which processes the other of the even harmonic and the odd harmonic included in the radio frequency signal;
- wherein, depending on each of said first harmonic processing circuits, a connecting point between said output terminal and said first harmonic processing circuit is at a different position in an arrangement direction of said transistors, and
- depending on each of said second harmonic processing circuits, a connecting point between said output terminal and said second harmonic processing circuit is at a different position in the arrangement direction.
