Hey all,
I am using AWR MWO to do some system simulations with VSS. My main question is about using data and modifying them.
So finally I have the result DB(C_GT(...))
I also plotted two maskes upper and lower that are around 0 dB.
The problem is that the DB C_GT is not around 0 db so I had to...
Hello all,
I read and watched that we can sue Sonnet LITE EM simulator in AWR MWO. However, I wonder that do I need an AXIEM license to use Sonnet Lite?
1. I am asking this since I do not have access to EM structure if I do not use an AXIEM license. (This is how Sonnet explained to use Sonnet...
I get your point it was simply my curiosity.
However, do u think to extract the parameters ( probably you mean curve fitting ) the how much frequency bandwidth measurement is important?
I am exciting at 2 GHz and loloking till the 5th harmonics So my are of interst is 2 GHZ ~ 10 GHz.
now that I...
Hello everyone
My aim is to model my diode. I want to use voltage controlled current source (look up table) in HSPICE parallel to a capacitor. (For the sake of easiness I decided to not use capacitor now). When I generated my HSPICE model by the code below I connected the V+ port of the VCCS to...
Aim:
:!: I want to design a Voltage controlled current source based on Look up table in ADS 2012. I searched and I could not find anything useful.
Problem:
I used DC simulation on a diode to get I-V curve. Now I want to make a current source generator based on the simulated values.
:?: What...
Hello everyone
I faced a weird problem and I want to know if you ever had such problem? (I am using ADS 2009)
I learned a technique to match transistor. (I used BJT RF transistor BFR91A)
1-set the operating problem
2-Get the S parameter of the transistor
4- then put S parameter in a "s2p_eqn"...
Thanks for replies but anyone answered the main question.
How is the Cripps method for impedance matching?
Is the following description about Cripps method true?
"By load line I calculate R_opt then by varying "X" in this formula : Z_L = R_opt ± j*X
we check which value is the best for maximum...
Thee are different methods of impedance matching for the power amplifier.
PA impedance matching techniques
a. Load pull methods
b. Cripps method
I know Load pull method, by varying output load impedance I check that "Delivered power" or "Power added efficiency" to get maximum based on my...
Dear all
My professor told me to design class A amplifier with this transistor **broken link removed**
and also design it by ADS2009.
in data sheet it is mentioned that for f≈2000MHz
Vds = 25 and IdQ=100ma
anyway
I have to use small Rload preferably 50 Ω.
I checked ADS DesignGuide for class A...
can anyone explain and say the reason of this sentence?
Any uniformly distributed random variable in the range (-a/2 to a/2) has an average power(variance) given by a^2/12.
is it ok?
Dear all
I drew an ideal ratrace in ADS and simulated it. I wanted to check the phase relation between them but I face a problem!!!
I thought that
1) phase(S(4,3)-S(4,2))
and
2) phase(S(4,3))-phase(S(4,2))
will end in same result but they are different.
which one is the correct one...
I want to design a mixer [ input : Lo@1.9Ghz , IF@100Mhz ] [ output : RF@2Ghz ]
I used ratrace and designed it in ADS so it will work good enough @1.95Ghz ( the average of LO and RF)
now the next step is connecting diode and ...
I have some basic idea. I read Maas book. For example I will use...
Dear all
I have this transistor " BLF6G21-10G " for my thesis.
I downloaded the model for ADS from here:
**broken link removed**
I downloaded the model but the Model needed some requirement as following:
"Model requires the RF LDMOS DesignKit library to be present (not included in the model...
@geneisxie: I am not sure about digital or analog.
@BigBoss: I should design it for a transceiver and I checked Gilbert Cell Mixer and it seems to me that it is not for transceiver but for receiver.
because in that design IF is connected to collector and RF is connected to base. so it is not...
