how to use pspice

Hi.

I am trying to simulate osc. in MWO. I think i should use spice file of BJT from

philips BFR93A. Unfortunately i failed to find the way to put data file.

Could you tell me how to import and use spice file, not s2p?

Only some error was found when i tried to use subblock of spice file, 'No port

found'.

I have to change something from spice file? VI curve also is not possible.

Somebody helps me to do something.

In MWO, click [Project] ---> [Add Netlist] ---> [Import Netlist] ---> File Type: Spice Netlist.

Hope can help u

bfr91a oscillator

I think you may may the spice file as a sub circuit nder simulation. Just so.

I do not get good result. In general, How do you simulate oscillator or

mixer part especially phase noise and VI curve whenever you do.

What kind of data file do you import?

Below is the one i'm trying to simulate. I just found in philips.

my purpose is to simulate phase noise and oscillation frequency.

Please do not ignore and give me favor.

Thank you.

Basically I tried to import subblock in schematic. It failed. I just v seen

some warning message that i would change the node of transistor.

but it's beyond my head.
