LVPECL to RF AMPLIFER

[jovin555]

I am using Dflipflop MC100EP31 and producing a ns pulse.Its ouput its LVPECL.I am interfacing it with a rf amplifier adl5592.So i connected the output of d flipflop to an ac coupling capacitor (1nF) and the output of the capacitor is connected to the rf input of IC.Is this the proper way to connect input?

Don't know what you want to achieve, but at least the LVPECL output needs a DC bias (load resistor).

How to calculate the load resistor calue?

Check the RF amp Power input spec.Your input should not exceed the AMP input range
