@Olin's assertion to resonant frequency is totally bogus. Water has absorptive properties over many decades of f without this resonance. http://www1.lsbu.ac.uk/water/microwave_water.html#loss This is a good reference but fails to discuss the ionic behaviors of contaminants.

IF you are an experienced EE and down vote this without comments you are in contempt of your own ego issue and have no business here. (more) |

A: Microwave oven interfering with WiFi on the 2.4GHz band Microwave Materials, Spectrum then EMI effects on SNR of WiFi, BT. There are a lot of measurable parameters in microwave dielectrics which affect; - Dielectric Constant , Dk between conductors and thus Impedance , Zo - scattering parameters in a transmission path from mismatch and loss...

For professional development, it is important to define the performance and assumptions desired before starting the design. I have some doubts on this design but then there are missing assumed values (more) |

Then s21 losses in the connector threads of 0.1dB is good 0.5dB is bad, so calibrated torque is important.

Now that you grasp the basics, the geometry is a big factor moving towards 5% of the wavelength and beyond. Although video SA's are 75 Ohms the std versions are 50 Ohms. But the only difference in coax is the ratio of the conductor radius for outer/inner.
In your example the small solder gap... (more) |
