Hi,
VDD_PA is tied to your Ant1/Ant2 Pin, If there's no problem with the soldering you can check that TX/RX antenna pin voltage is OK. You can also verify the signal at the RX antenna pin using spectrum analyzer. This will help you to know if your matching network is soldered properly. First...
Hi,
Yes we can, but we shouldn't expect ADS to perform like Mentor Graphics or Altium does. ADS layout is more on RF.
I've attached the example layout, we can also output the file on dxf , gerber and other format.
Goodluck...
starting salary in singapore
For expat, the minimum salary for eng'r to have EP is 2.5K. Note that major companies used to bargain down to 2K.
The problem is the rent of the HDB which now can cost you from 1k ~ 1.5K for 3 rooms that you can share for 3 person.
Can you provide more information than product promotional link.
Does anybody can upload a doc about their Two-Tone Approach for TOI simulation? specially for linear device. ADS , HFSS and Ansoft format should be fine.
Thanks
Hi,
ADS already have this capability since version 1.1. It has a Meas Eqn component located at Simulation S_Param and Simulation -HB pallete that serve that purpose, the flexibility of ADS lies on the built in Eqn and you can display it graphically in Data Display windows.
Goodluck
Re: What each component does
Hi,
The documentation for this component is really short, but you can check the multitone_test example, four component were used for RF/Biasing circuitry Isolation.
Two RFC are used to isolate the power supply from high frequency RF signal and two DC blocking...
Hi,
To convert S to Y use
Y11 = 1/Zo((1-S11)(1+S22) + S12S21/((1-S11)(1+S22) - S12S21))
Y12 = 1/Zo(-2S12/((1-S11)(1+S22) - S12S21))
Y21 = 1/Zo(-2S21/((1-S11)(1+S22) - S12S21))
Y22 = 1/Zo((1+S11)(1-S22) + S12S21/((1-S11)(1+S22) - S12S21))
You can also simulate that with ADS using function...
measure resonance of pcb
Hi,
Dielectric constant is depending on your operating frequency. A more accurate value of εr is determined by measuring the actual propagation delay of a signal in a trace using Time Domain Reflectometer with unit of inches/ns or ps/inch.
For example at 10MHz the...
Hi,
Take note that equation above is valid for uncoated trace or copper, PCB manufacturer normally cover the trace or copper with mask with a thickness of 8-10 mills and that will turn the equation to;
er' = er{ 1 - pow(e, ((-1.55*(H+T+M))/H) ) }
where
e =euler's constant
H =Trace distance...
rf+99 software
Hi,
Looking for a basic knowledge you should grab some books, but take note that No books will give you all the knowledge that you need so you need to spend more money.
For RF circuit simulator, If you have opportunity to purchase I recommend ADS from Agilent, maybe because...
