transformer amplifier
Hi, i'm currently working on an RF amplifier, on which i currently don't have the schematic on the computer i'm using now. But basically, it looks like the circuit over here: , except that after the transistors it goes directly to a transformer and then output. I am using OrCAD to simulate it right now, and i'm having trouble with simulating the transformer(as the manufacturer refuses to give me some information, the only information available are ohm ratio, freq range, insertion loss and input r. loss). How do you think i can get around this?and also i'm looking for a transistor (FET especially) for my circuit. The frequency range is 0-300Mhz. i am using blf202 but i can't get the orcad library/model for it. Is there any suggestion of what transistor i can use?and by the way, both transformer are tt4-1a+ by minicircuits. Thanks
