Hi,
Does anyone know how to calculate the dielectric loss and metal loss in the field calculator?
Is it simply by integrating the volume loss on a dielectric or metal layer?
How is expressed the output value ? in dB ?
What's the link with the S-parameters ?
Thanks in advanced,
Hi,
I've to design a kit of test-structures for modeling CPW lines on high-resistivty silicon wafer. The goal is to perform de-embedding with TRL, Half-Thru method, etc...
I have some basic questions about the layout of the de-embedding structures.
For the OPEN structure:
- What is the distance...
Hi Carole,
What says jiboune256 is true if you allow the solver for more than 1 mode. It is on the settings of the waveport.
So if you need to see of higher modes propagate, do not forget to increase the number of solved ports.
As you say, the S-parameters refers to 50Ohms, but more generally to the reference impedance of the measurement system.
For this, the S-parameters are normalized to the reference impedance when exported and thus they become from the impedance. We talk about "generalized S-parameters".
By this...
Hi,
When defining the boundary conditions, it is important to surround the air box (or it can also be the vacuum box) by a radiating conditions that enable the wave to radiate infinitely far into space.
But Ansoft documentation does not precise how big should be the air box.
I know that a too...
Hi,
I have not used momentum for years now but i remember having similar issues at that time.
I solved the problem by loading substrate definition example of GaAs substrate for instance or PCB materials, in order to see how the layer where mapped. The documentation of momentum is also well...
Re: HFSS surprising bad precision on capacitor modeling
Interesting !
Do you have an idea of the cost for a licence of this software ?
Thnaks in advance.
Re: hfss mesh outside
Hi Timof,
I'm interested in knowing more about "random walk based capacitance extraction". Can you please give references of article, pdf files or presentations about it ?
Which software do you use in which the method is implemented ?
Thanks for your answer,
Xof
Hi everybody,
I want to launch HFSS simulation in batch mode in v11.
Below is a syntax I use that works:
hfss.exe -batchsolve "C:\Documents and Settings\Administrator\My Documents\HFSS\Tline.hfss"
I'd like to specify a design name within the project.
Is anyone who knows the syntax ?
Thank...
Hi,
Thanks all for your fast answer!
The P0.1dB is interesting. Vfone, you wrote it is a "very important specification of high power switches".
Can you tell more about this spec ? The why and the how ? It's pretty hard to find litterature about this point.
Thanks in advance,
Hi everybody !
I've found that switch from Hittite having a IP3 of 74dBm. It's a T/R switch for Cellular/3G, TD-SCDMA, PMR,...
I do understand the necessity of having very high IP3.
But such a value of 74dBm is really needed ? For an amplifier of the same manufacturer, the highest IP3 I've...
ansoft designer price
Hi,
Does anyone of you have an idea of the cost of licenses for:
_ ADS
_ Ansoft Designer
_ Microwave office
Thank you in advance for your answers,

Hi everybody,
I'm using HFSS in order to simulate accurately CPW lines characteristics on a micro-machining process.
The CPW line conductors are deposited in several steps leading to a particular lateral profile (see attached file: Tline-profile.gif). In few words, the...
