when i used wave port i defined radiation boundary as BOX and it touch the wave port in same surface ... so i changed the port so i should change the radiation boundary
right ??
yes I used lumped port but the results are shifted ... i dont knew why ??
is there any modification in Radiation boundary i made it as i did in wave port .. is that right ??
Hello
I designed a patched antenna to resonate at 5GHz using HFSS but the problem is when i fed it using Lumped port the frequency shifted by one GHz and if i used wave port the result is good ...
Please Can anyone help me to knew why does this happened ?
Thanks in advance
Hello .. i am designing direct conversion Passive Mixer and i want to knew how to perform IIP3 test to direct conversion
and how to plot the Conversion Gain with LO ... i am using Cadence tools
thanks in advance
so what about difference between passive voltage mixer and passive Current mixer .....
i think the difference between voltage and current is in NF in voltage is higher than Current Mixing.
but which one is high Linearity IIP3 ?
thanks vfone... but i mean is there any method to reject this noise form the image frequency , I think that will make SSB NF equals to DSB NF ..right ??
Hello all please i want to know
1. which one of them have more flicker noise ?
2. How can we remove the image noise to make SSB NF equals to DSB NF ?
3. what is the difference between V-V mixer and V-I-V mixer ?
thanks in advance
