The lowest mode of propagation is TE01 with a cutoff of 1.64*diameter therefor your waveguide is cut off. 1/4 wavelength of cut-off waveguide is enough to extinct all of the evinescent energy.
If you establish your reference plane at the IC pin, you can use a 50 ohm load at that point (with no IC). use three standards O-S-L at that point for the s11,s22 calibration. the thru will have some line length (from pin to pin) and some impedance that you will have to calculate for the thru...
My humble attempt to answer these deep questions.
Question 1:
Electrical Limitation: Fundemental material parameters effects such as saturated drift velocity, mobility, gate length or base thickness, various resistive and reactive parasitic elements.
Thermal Limitation: Junction temperature...
How about a two interlocked two door scheme, 1-open, 1-closed and visa-versa. with RF gasketed doors. The chickens would need to be spaced approptiately to keep from getting the doors jambed though.
A quick reality check would indicate that your "waveguide" is operating in a higher mode (I am use to TE10 only) Yours may be TE6,2? in this case you would need an array of the ferrite rods 6 top and 6 bottom (evenly spaced), arrayed at a longitudinal spacing on the order of 1.2"...
It sounds like you want to build a waveguide attenuator with probably a high level of attenuation. There are various sources of information available. The rods are probably high temperature lossy ferrite material such as emersons mf-500. I would place them at 1/4 guide wavelengths apart such to...
Any sources for motor generators or invertors that will convert 208 or 480v 60Hz to 220V 50Hz (single phase or 3-phase) Motor generators are prefered (from our 60/400 hz experiences) Power output in the 10KW range.
Thanks
HP Basic always worked well for me. The GPIB card can get setup using an autostart script, that you can select the options for your GPIB card (the hardest part). However HP basic has gone the way of latin it would appear, a dead languange.
I personally do not think that the isolated grounding is that important today (if ever). Since the isolated grounding conductor is ran in the same conduit as the rest of the conductors, common-mode noise will still be induced upon it, Plus the inductance of the single wire (isolated ground) is...
The US navy no longer trust (most) microproccessor AFD drives on crane hoist motors to be shut down (ie upper limit switch) using the AFD's built in logic/ discrete input. Therefore I am faced with the prospect of opening the three legs of the input or output of the AFD. I am worried about...
depending on your frequency band, you could calibrate into standard 300 ohm twinlead using a off-the shelf 75-to 300ohm balun & using a short, 1/6lambda, 1/3 lambda shorts or 300 ohm load and open cal standards whatever you prefer, or using tsd etc. then using the measured reflection coefficient...
