Dual Switching Diode and OpAmp
According to the datasheet, This op-amp is current feedback for RF applications only, with supply rails of +/- 5 volts.

It MUST have a balanced bipolar power supply.

Feedback and gain resistors are normally less than 1K ohm.

The diode at the input is to clamp input voltage close to video p-p voltage, about +/- 1 volt. This op-amp normally expects signals not over 0.5 volts positive or negative.

This is a high performance op-amp that cannot be used on a breadboard. It is meant for custom boards with adequate ground plane and power and bypass capacitors. Input and output are usually 50 to 75 ohm RF connectors or traces.

This is an example (#48) from the datasheet. Notice there are NO capacitors on the input, output or feedback lines. If there were they would be no more than a few pF, to avoid instability.
