Broadband buffer amplifier capable of driving 50Ω loads

Since the emitter output device Tfi and the output transistor Tr. of the auxiliary stage are interconnected
, the fluctuation of the output DC level caused by P zri can be reduced.
The offset adjustment between the output 1 inputs is done by VRi .
  ． Use the inverting output of the collector pole of 5ffrI to change the current of the current Miller
circuit composed of Trl and Tf4 , and use Tf. and Tr4 for push-pull output.     Due to the use of two-stage amplification, there will be a time lag during conversion. In order to increase the conversion speed, the pulse peaking capacitor Cl (several hundred picos) should be connected in parallel to the amplifier and adjusted during installation until the square Reluctant to leave
