High frequency circuit

A high-frequency circuit comprising:

• a plurality of amplifying blocks arranged in multi-stages, including at least a first-stage amplifying block and a final-stage amplifying block,
• each of the plurality of amplifying blocks including at least an amplifying element, a choke inductor, and a by-pass capacitor, in which a power terminal of the amplifying element is connected to one end of the choke inductor, the other end of the choke inductor is connected to one end of the by-pass capacitor, and the other end of the by-pass capacitor is grounded,
• electric power being supplied from a common power terminal to the amplifying elements in the respective amplifying blocks via the choke inductors in the respective amplifying blocks,
• wherein a resistive element is provided between the common power terminal and the choke inductor in the amplifying block other than the final-stage amplifying block so that the electric power is supplied to the amplifying element in the amplifying block other than the final-stage amplifying block via the resistive element and the choke inductor, and
• wherein at least the amplifying elements, the choke inductors, the by-pass capacitors, and the resistive element are provided on a same substrate.
