I have an Antenna system using two patch antennas, and I'm trying to determine the SNRin and SNRout of the system. I'm trying to determine the noise figure - is there a way to do it using scattering parameters? Thanks!
One of my professors made an X-band cavity resonator by putting together, end to end, two X281A coaxial waveguide adapters (n-type) with cut center pins. It works pretty well - but I need some more information. Does anyone know where can I find some more information on this setup...
The article on windowing functions sounds great - if you can find that article that would be greatly appreciated. I've implemented the window two ways, first using the mathematical gating function of my DPO7000 series oscilloscope, second just dumping the data into MATLAB and deleted the data...
I thought about the directional coupler in reverse. I'm actually using a circulator - but it accomplishes the same thing. The problem is that my reflected pulse contains both the resonator response and the reflected interrogation pulse. The resonator only absorbs about 4-5dB at the resonate...
I am measuring the reflected power of a resonator for potential wireless applications. I'm pulsing the resonator with a 10.64GHz (resonate freq) pulsed waveform (10ns pulse width, 200ns period). Use an oscilloscope, it's easy to see the reflected pulse - with a maximum voltage just after the...
