Microwave Office - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

Hello. Does anyone have any experience with using Microwave Office (AWR)? It does not seem to have any transistor models available. I am trying to simulate certain circuits that involve RF transistors but there are only generic ones with empty models. Is there a way of adding models to the library or do I have to fill in the model parameters (internal capacitances, current gain,...) for every transistor I want to use? Thanks a lot for the help.

Not sure what you mean about not having any models; generic models or vendor models? It's got 16 generic BJT models and 37 generic FET models. Anything else it's up to the vendor to provide. Did you install the vendor component libraries? If not then they should still be available as long as you are not behind a strict firewall.

There are a few ways to use models.

1) Chose one from the vendor library.

2) Enter the model parameters manually into a generic model. Need teh vendors SPICE or other model parameters for this.

3) Do the same as 2 but use a model block and instance (really ment for IC scaled models)

4) Import a spice netlist. This will not work for macro-models that use VSWITCH elements since ideal switches really can't be simulated in harmonic balance. However if you have the HSPICE option you can edit it by hand to replace the VSWITCH with a transconductance element.

Dear Rising_Phoenix,

You can find RF transistor models in the non-linear library. Thanks.

Best Regards,

AWR has one knowledge base in their homepage.

You can access the knowledge base with a free account.

There are a lot of example and tutorial material in the knowledge base.
