Hello ,I have the following amplifyer PMA5-83-2W+ link shown below.
I am building a sequencer for this device.The problem is that i dont have any data regarding what will be the Load .
I dont have any model, The data sheet doesnt say what is the equivalent gate and drain loads.
The manufacturer doesnt have any answers.
So I suppose I am not the first person who doesnt have any simulation model of the amplyier and manages to design a sequencer for it.
Is there some methods I could use?
Thanks.

In order to remove enough error from just the probes is statistics.
Notice the symmetry difference between generations of PMA with regard to copper.
Does a doctor with classified information share everything with the hospital staff?
The frustration is to set aside your identity in order to cope when it does'nt matter anymore
then just get that pony as close as you can with experience. It's none of their business.

UPDATE:
Hello , so Its pure resistivefrom from data data sheet page 3 below a partially working sequencer and the outputs are shown in red arrows.
So for example My load at Vdd will be 30Ohm
But in real life as you can see in the data sheet photo I have capacitances too.
Capacitance on the load will slow down the pulse on one hand but will make the voltage stable.
How do you reccomend to see how much capacitance i need to put at the end of the Vg1 Vdd ?
The data sheet is talking about manual switching of the voltages here i have sequences and wrong capacitances at the load could ruing the sequence.
Thanks.
