As a crude method to simulate you can use a stripline element, make Er =1.0, the Thickness &width = the diameter of the wire, L = 1cm , and the substraight
height will be your closest ground reference distance.
But at 3-10GHz expect orders of magnitude variation between simulation and...
You should take an IP3 measurement at ~10dB backed off from the PA's / RF Chains P1dB point. Thus reduce the I/P pwr till the O/P pwr is ~ 10dB lower than the P1dB point.
You need to be in the Amp's linear region. If you put too much power you will be compressing Amplifiers, and the IP3 will...
From memory.
You need to create a file of the modulated waveform (Look at the literature from Agilent on how to do that ). Once you have the file in memory you select the segment/waveform. On the same window when you select / load the file there is a setup option. It is the frequency of the...
I think there was a misnomer .
dB vs dBm
dB is a ratio , and dBm is a power referenced to 1mW.
So 60dB + 60 dB is not a clear statement. Unless you mean a factor of 1000 + another factor of 1000 ?...
60dBm + 60dBm should mean adding 1,000 W with 1,000 W which =2,000 W & 2,000 W = 63dBm ...
Just open excel, then Click "File" -->"Open" Search for this file, and open it. Then select the "Delimited" option, and click next. Then select if you need Tab, Comma, Space, or Special Charter
to partition you file properly.
Cheers
These are called "Min-Loss Pads". There is a minimum amount of loss that you must incur when going from one
Zo value to another.
Here is a good tutorial.

You can also search for the Pi / T Pad attenuator tools on line and see what...
Did you go in to "Reg Edit" and make sure the ADS software was deleted from there too ?

Your question is not too clear. First it sounds like you have a 3-port network, and depending on which port you
consider the input and output you might want S23 or S31....
You should show a diagram or the layout of your design and you might get a response.
You can try to graph your simulation...
I think you have a few issues.
1) The TL1 is acting as a matched load at the input of your circuit, and TL 2 and the Didoes ect is in parallel so
that will cause a mismatch.
2) Your third terminal of your Diode is not connected to anything, so it's a high impermanence open, and does not...
First you should always search this website for your question. Then after you find all the
info that has already been given, form a better question that has not been answered.
When you use Strip lines / TL you will have to put the substrate information on the MSUB. This defines an
assumed return path on the ground plane.
Just go make a 1Lamda Zo TL in the schematic then send it to Momentum(Layout) and see how they
defined that circuit/PCB. This should help.
With out more info all answers/suggestions a based on assumptions !
So if you have this antenna on a PCB you can changes the εr to a higher number. This will reduce the
length of λ so with the same real estate you will have a lower resonate frequency .
If you double your εr of the PCB that...
