It is teste with two insturment from different manufacturer. The result is almost the same.

good idea. I may rplace everythins in series with 0 ohm resistor/capacitors and measure again.
Hello Every one,
I have a wifi enabled chip. The module has been designed to use this chip for wifi and BT.
I did EVM measurement for WiFi. All bands&bws are ok.
The 6G band shows high EVM in 80 BW signals.
It is also independant of power. so it is not related to PA saturation.
Do you know what...
Actually the port in left side is regulator output and the port in right side is the LDO input.
I wanted to see the difference of two structure above.
There is no high frequency signals there.
Would you recommend to I do a transient simulation using spice models instead of frequency sweep...
Hello everyone.
I have a general question?
I want to get max throughput in a WiFi FE in 5 GHz band. Normally I need high degree of modulation. 1024 QAM I think. As I know it is very sensitive to phase noise.
At the end question is that how can I reach throughout throughput? Which one os more...
Many thanks senilicus,
I know that it seems super easy but for me it was very hard to find!
Next question comes up; The "update managed block" dialog is empty. Do you know the reason?
Thanks
Hello all,
I have a managed blocks in Xpedition EDM Design Cockpit. I modify it and doing the check in. After I open the project which uses this managed blocks, I dont see the changes I applied!
For me it seems;
1- in one port like a quarter-wavelength matching
2- in the other port a matching network includes at least one parallel capacitor and one parallel inductor made by microstrip lines (and also maybe some LC resonators!).
Anyhow, they used some special techniques using that...
Hello,
I'm trying to realize a bandpass filter using a microstrip coupled line.
There is a possibility in ADS to simulate these structures (as shown below).
But I don't have ADS. Is there any open-source tool to do it for me?
Can I do it using Qucs? ( I had a look on Qucs, and it doesn't...
For GPS applications, if you want an on-board antenna you will need a big ground plane for good antenna performance.
If possible use an external active antenna (antenna + LNA) and connect it using one of the tiny on-board coax connectors like these here
