Abstract
A radio frequency signal RF is input to a base of each of transistors TRthrough TRn via a corresponding capacitor among capacitors Cthrough Cn, is amplified, and is output from a collector of each of the transistors TRthrough TRn. An emitter of each of the transistors TRthrough TRn is grounded. A bias voltage DC given from a bias circuit Bias is supplied to the base of each of the transistors TRthrough TRn via a corresponding resistor among resistors Rathrough Ran. A signal line for the bias voltage DC is connected to an input line for the radio frequency signal RF via the bridge resistor R in a direct current manner.
