10 Apr 2008 19:07 arf448 pspice model

Hello, i'm having problems to probe the pspice model of a RF MOSFET.
the mosfet is : ARF446AB froam Microsemi(http://www.microsemi.com/catalog/part.asp?PARTNO=ARF446G). In their site they post a Pspice model for their transistors.The model for this one is:

**********
*SRC=ARF446;ARF446A/B;MOSFETs N;Power >100V;APT 1000V 8A 1.5ohm TO247-rf
*SYM=POWMOSN
.SUBCKT ARF446 10 20 30
* TERMINALS: D G S
M1 1 2 3 3 DMOS L=1U W=1U
RD 10 1 0.712
RS 40 3 38.5M
RG 20 2 .2
CGS 2 3 1.47N
EGD 12 0 2 1 1
VFB 14 0 0
FFB 2 1 VFB 1
CGD 13 14 1.85N
R1 13 0 1
D1 12 13 DLIM
DDG 15 14 DCGD
R2 12 15 1
D2 15 0 DLIM
DSD 3 10 DSUB
LS 30 40 3N
.MODEL DMOS NMOS (LEVEL=1 LAMBDA=85.3u VTO=3.8 KP=6.06)
.MODEL DCGD D (CJO=1.85N VJ=0.6 M=0.6 Cool

.MODEL DSUB D (IS=31.1N N=1.5 RS=0.113 BV=1K CJO=519P VJ=0.8 M=0.42 TT=258N)
.MODEL DLIM D (IS=100U)
.ENDS

I'm trying to simulate the test circuit from his datasheet. But I´m having problems
with the simulator. I using the microwave office but i'm not sure that is the correct simulator for this spice model.
Please can anyone could help with this problem i'll apreciate your help
thanks

Hello, thanks for answer.
I post 2 project:
PA: is using the netlist anda
PA4: is with schematic basic on a paper of the ARF448.
all the info is in the application note(relate with the schematic model of the mosfet)
I trying to simulate the test circuit from his datasheet.

THANKS for the help

you can use pspice simulator

I am trying to simulate an rf power amplifier for rfid application and I want to implement arf model for pspice.

I need the library .lib for the model simulation and the library .slb for the graphic simbol to used for schematics.
