From graphs attached to huytergan post on Feb7 it may be that the initial simulation (what simulator?) it was configured as LHCP for RECEPTION. Then the gain simulation it may be, by default, TRANSMISSION.
Same circular pol. antenna, for instance a simple helix, receiving LHCP if also used in...
It may be the case that knowing what transistor(s) is going to show matching networks sometimes made available in transistor datasheets.
what is the transistor(s) reference? what manufacturer did you choose?
this antenna has to be safely anchored to stand winds up to 120km/h, at least. This particular grid operator requiring a 1.5m rod or antenna wiring that you intend to install to stand higher wind speed.
Have you asked the grid operator for written permission?
They may only allow approved...
Hi supernano this is JohnBG2021, could you please post a view of the part of the circuit where you intend to place the resonator?
please include a visual or side notation scale reference so readers know how wide/long is the track and how close or far from track have you tried so far.

Hi c_mitra, when I mentioned that I'd test it, I implied: if time, money, space, if at work only when line manager requested so.
I agree that these 'endurance tests' should be the exception rather that the rule, even in product design/development. After all the manufacturer has already carried...
Wonderful answer danadakk.
I agree with Nuvoletta that [dBc] is often used as a simple [dB] distance between spectral carriers.
But as danadakk points out with the R&S app : [dBc] is the standard way to measure whatever spectral level found at 1Hz from carrier, by default, or [dBc/Hz] when at...
thanks FvM for pointing out these 2 corrections. If my question I'd buy samples from different manufacturers and test. Experimental results are more reliable than any assurance on paper that a certain component can do this or can go that far.
I agree.
[dB] and [dBc] are dimensionless but often people also shorten [dBW] to just [dB] now Power, [dBW] being the ratio between a power measurement and 1W reference signal assumed reliable, now no longer dimensionless, and [dBmW] is also often shortened to [dBm] again Power measured in...
Hi this is JohnBG2021. I’d like to refine my answer to this question with the following lines:
1. I agree with c_mitra , Vicor’s note I mentioned earlier on apparently shows capacitors XY safety rating, but only includes some figures for Y type, and is an application note more focussed on...
A single lambda/4 transmission line is called narrow band because if applied correctly it inverts impedance between ports, with reasonably large enough |s11|, but |s11| quickly rises on both sides of the single frequency chosen to calculate the characteristic impedance.
lambda/4 transmission...
Hi ZionWil this is JohnBG2021. Actually the moderator has accepted all my comments for your question. I have removed slides 32 33, because with the circuit with Id(Vg) graphs it was enough.
Have you noticed that the moderator uses Keysight logo?
I have asked permission for reproduction to Mr...
