This configuration utilizes the wide bandwidth aod speed of HA-2540. plus the output capability of HA5033. Stabilization circuitry is avoided by operating HA-2540 at a closed loop gain of 10, while maintaining an overall block gain of unity. A maximum block gain of 3 is recommended to prevent signal distortion.
This circuit was tested for differential phase aod differential gain using a Tektronix 520A vector scope and a Tektronix 146 video signal generator. Both differential phase and differential gain were too small to be measured.
