UWB switch
Hi,
What are the criteria for an UWB switch? In other words, what are the conditions that we say that this swicth is an UWB switch? Also, can you provide me good books on UWB switch for beginners?
Thanks,

Re: source and antenna
Thanks for the info. So, if my generator is a ultra wide band (impulse) this means that I can use all types of antenna.
Thanks,
Mica
Hello,
I need some clarifications. Please correct me if I'm wrong. Here is my summary of the problem which I don't quit understand. The source ( feed the antenna) will attach to the antenna. Quit obvious. The only thing is to be sure to match the source to the antenna to avoid inefficiency...
Thanks for your response.
What is the difference when you apply an impluse to your dipole and a sine wave? Correct me if I'm wrong, an impluse have a large spectrum of frequency then a sine wave which have a single frequency. So, if my antenna is a dipole, it is not necessarily to have an...
Hello,
A generator gives a 100 volts output in 3 secondes and it connected to an dipole antenna (assuming no loss in connection). What will be the fequency of this output that can radiated this maximum energy? Because a dipole its lenght is lamda/2 to radiate the maximum energy. How can you...
pspice model level
Thanks, I have a lot of problems. What is the cheap version that I can buy? I don't want the student version because I can get output data in txt format.
Thanks,
Mica
Hi,
Where can I find an evaluation version of PSpice ? I don't want the student version and I have download PSpice from OrCAD. It is very complicated. It doesn't read schematic file which I have created from PSpice version student (MicroSim). Can some help me?
Regards,
Mica
Input impedance
Hi,
I'm a little bit confuse. Concerning the input impedance of an antenna, I have excited a dipole with a pluse (gaussian). The output data at each frequency is associated with one input impedance. Is this mean that to have that energy radiated I have to match this impedance...
Output data
Hi,
Can someone provide me an output data of an impulse in PSpice, the width of this impulse is about 1 nanosec (voltage vs time)?
Thanks,
Mica
Re: Few questions on Ansys 8.1 and Ansys Workbench Suites 8.
No, Ansys Mutlphysics can be used for HIGH frequency only. But if you want to use for LOW frequency, you have to get an add-on module which is " Emag".
