Hi guys!,
I'm wondering if there is something like an emulator for testing device regarding car CPU. You usually have to buy specialized stuff but it always requires a serial connection so a PC with adequate software could emulate all.
Can anybody help me?
thanks pkn
If you talk of patch antennas, I say you are right. I think your problem is another. You are asking if you can build an antenna smaller than lamda/4.
In general you cannot say this, because you should demnstrate that a solution for the Maxwell equation exists for any geometric structure.
In case...
Types of antenna
WHat do you mean by asking the smallest antenna?!?
Halfwave dipole is just one type of realizable antenna
I think you should also say in which frequency range you are planning to work.
For example at very low frequency (up to kHz) you can use hertzian dipoles (very poor...
DCF77
Has anybody experienced with DCF77 signal?!?
I am designing a receiver and singal processing part.
TRF I think is one possible solution, Superetherodyne is excessive.
Suggestions and difficulties encountered are welcome.
Thank you.
Remember however, that if you use nonlinear simulation you'd better do one-tone simulation. I suggest you also to look at Pin-Pout curve, which shows the compression point, look at harmonics level that should be kept not so high and at PAE = Pout/(Pin+PDC)
First, you have to choose the class of your PA such as A, AB, B, C, F, G, H, HG... which implies different choices... say we choose class A that means that you have to bias your transistor in the middle of the V-I characterics... for your frequency range 2GHz I would not use distributed...
Please be more precise with design specifications and include bandwidth, output-power level and transistor used. Have you tried to simulate with MicrowaveOffice?
