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
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
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.

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
In summary, 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
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.

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
