Disclosed is a wide band high output amplifier in which a field effect transistor is used as an output element, in which a constant resistance circuit is inserted between the drain terminal of the field effect transistor and a load capacitance such that the impedance characteristic is a constant resistive value and provides a peaking function across the load capacitance so as to improve the high frequency characteristic of the amplifier without increasing the imput impedance of the field effect transistor.
