Hi guys,

Anyone got a spice model, datasheet or both for the BFG194?

Thanks,

Hi guys,

Anyone got a spice model, datasheet or both for the BFG194?

Hello Paul,
Click to expand...
the datasheet is on the Infineon website. www.infineon.com
Search for products -> transistors -> Discrete -> RF transistors.

I recommend to think of the BFG194 as a three times the chip area
BFT192 in a SOT223 package. The datasheets of both transistors
really look very similar, except the three times current and capacitances.
The SPICE model for the BFT92 is in the datasheet and on the Infineon
website.
The package models are also there.

The proposed model is a subcircuit. Thus it requires a subcircuit
symbol in LTSPICE. You can either modify the standard transistor
symbol to become a subcircuit symbol or you use the universal
xpnp.asy symbol.

Best regards,
Helmut

Hello Paul,
there has been a missing inductor in my subcircuit and I have
changed one inductor from 0 to 0.001nH. A test circuit file should
be already in your email when you read this.

Best regards,
Helmut

An LTSPICE symbol for any PNP transistor subcircuit "XPNP.ASY" .
Put this symbol into your project (working) directory.
You can add it then with the LTSPICE add "Component" menu.
The subcircuit definition must be addd directly or via an
include file (.INCLUDE filename) to the schematic.
