Integrated high frequency amplifier

An integrated high frequency amplifier comprising a pair of first and second transistors with their emitter electrodes connected in common, said first and second transistors constituting a differential amplifier, a third transistor, a resistor connecting a base electrode of said third transistor to said commonly connected emitter electrodes in an emitter follower fashion, fourth and fifth transistors, means for connecting a base electrode of said fourth transistor to an emitter electrode of said third transistor, a sixth transistor with its base electrode connected to a collector electrode of said second transistor, serially connected resistors connected between a base electrode of said fifth transistor and an emitter electrode of said sixth transistor, means for connecting a junction between said serially connected resistors to a base electrode of said second transistor, a capacitor connected between base and collector electrodes of said fifth transistor, said fourth and fifth transistors, said serially connected resistors, and said capacitor constituting a differential integrating amplifier, means for applying an input signal to a base electrode of said first transistor, and means for deriving out an output from the emitter electrode of said sixth transistor.
