Hello, So basickly its a filter to pass the pulse to the amplifier

In Ltspice I have made equivalent circuit with AC transfer function response with 5Mhz BW 69Mhz.

the original circuit acts good but as you can see in the last photo When i lowered the 1.1uH to 100nH an the pulse goes threw much better.

One dilemma I have regarding the load.I will connect this circuit to spectrum analyzer.

What load do i need to put in the simulation to test the response?

Thanks.
