Best simulator? - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

I am a graduate student in USA (born here as citizen, not visa) and want to know what simulators are used by
majority of engineers doing defense contractor work; ie, L-Mart, Northrop, etc. I like Eagleware, but want to use
what I am likely to use when working in another two years. Any advice? Thanks.

The fact is
there are a lot of software packages out there and learning any one package does not guarantee that it will be
used in your future place of employment. Agilent's ADS seems to be the big name in RF/microwave simulators.
However, other companies like Eagleware, Applied Wave Research (Microwave Office), Aplac, et al, make very
good software and a lot of big name companies use them. I personally don't like the ADS interface - never have
liked any of the EESOF/HP/Agilent software interfaces.
I'd say the most improtant thing would be to build
proficieny in simulations in general, and the skills will migrate to any platform.
Well, that's my opinion.

For commercial /
academic work I think Agilent technologies' ADS is an excellent simulator. I have used it to design circuits up to
the 5 GHz.
The "design guides" facility is an incredibly useful tool that speeds up the process. However I
would strongly advise anyone to understand throughly what the engine does, whether you are doing steady
state/transient/ harmonic balance analysis etc.
The 2.5D EM simulator Momentum is really good, based on
integral equations that allow muti layer dielectric problems to be reduced to simpler integral equations and solve
by using the method of moments.
I am simply in awe of Agilent Technologies' kit.

Our company is currently using
Microwave Office. In the past, we've used the EESof packages (now owned by Agilent). I've worked with EESof quite
a bit and Microwave Office a little. We also have Ansoft HFSS for EM simulation.
My recommendation is to go
with somehting that you think is straightforward to use, but MAKE SURE that you understand how the simulator
works. None of them are perfect and each introduces modeling errors of some type or another.
I'd say that for most simulation tools, how you use it is more important than the actual choice of software
(assuming it works at all).

Welcome to forum!
There are many RF & MW software design tools
in the market. Eagleware, Microwave Office, Agilent, Filtronic… etc are reliable and accurate software design
tools. They all can be competitor. It all depends on design and applications. I strongly trust that defense
contractor companies will NOT disclosure what software design tools they use to simulate their design. They can
make their own version and for different applications. This is due to national security issues. Come on, that is a
common sense! However, RF circuitry is RF circuitry, electronics is electronics, physics is physics and
intelligent one’s can always come close or even a match “apples to apples” towards any military hardware or
software design and/or applications. If I were you, I wouldn’t give too much concern about what type software
design tools defense contractor companies can use, but what will benefit your career, dream and happiness in the
future. That’s my sole opinion. Good luck!

I used 3 types of RF simulators: Microwave
Office, Agilent-ADS and Eagleware.
The best performance for Non-Linear applications is the ADS, with superb
HB engine and accurate models of Non-Linear devices. I used it to design Analog PD linearizer for Power
Amplifiers. It gave excellent results almost the same as measured in the lab.
For EM simulations and linear
simulations the best is Microwave Office, because of its more convenient user interface. I hope that Agilent will
learn to make theirt use interface a bit more friendly.

wow. Sonnet works with 6% error
for EM filters.
Microwave office has quite good interface, works nicely. The EM part gives ill-fated results.
Software is like food. Good from home, bad from third party.
Where to download ADS kit

There are many recommendation for
Agilent ADS. Can I know if they is any ADS kit for download which can be used.

i think the most used simulator is ADS , and MWO
but the ADS
is the most powerfull as i think
i am using it , and enjoying the use of it , and also i am using MWO , but
i donot like it
