I know they have a bandwidth and that related to the length, as you can only move the load over some distance, and that needs to be a significant fraction of a wavelength. Hence a 1 MHz sliding load would be a bit big!!!
But I thought the basic construction was of partically conductive...
I've got a Maury Microwave sliding load of unknown history which is fitted with an APC-7 connector. Is there any quick tests I can do to see whether the device is basically functional or not? A DVM shows 0 Ohms between the inner and outer conductors, which made no sence to me, as I was expecting...
I suspect with manual intervention, you can make the mesh finer in the region of interest, and course elsewhere. I don't know how to do it, but I believe it can be done.
Basic question
I want to draw a model in HFSS, with one of the parameters being a length 'L'. A want to sweep the frequency over a range (say 3-6 GHz), but have the length L always a half wave long. So a table of L vs frequency would be:
3 GHz - 50 mm
4 GHz - 37.5 mm
5 GHz - 30 mm
6 GHz -...
Thank you It only appears to have the female though.
I had tried a few manufacturers and could not find the detail I wanted. The MIL standard looks more like what I wanted, but it only seems to have the femals for all connector types - N, SMA. SC, C etc.
I don't actually want to build them -...
I'm looking for sufficient information about the N connector such that I could model one in HFSS, or better still get someone to make one from a drawing, rather than copy one. In other words, I'm looking for a fully dimensioned drawing.
Can anyone help?
A better question would be if it is advisable to approach your project like this. It would be far more useful to you as a student if you stated what problems you had trying to write the code, post your attempts, and let others advise you of improved approaches to take. Your request might well...
HFSS - trying to find S-parameters of an open N plug at reference plane
I'm looking for a cheap way to make an "open" standard for a VNA calibration kit. One way is to just leave the N plug open. Agilent's FieldFox range of portable VNAs have an optional "QuickCal" which uses the RF connector...
Why would I want to have someone as a friend on here? Apart from giving me some points, which I don't care about, what do friends actually achieve here? I tend to ignore such requests to be friends with a total stranger, but perhaps I am overlooking something.
Frequency stability is often important, which changes both due to aging and temperature. I'm no expert on this. I don't think phase noise is set too much by the crystal, but rather by the oscillator that it is built into.
However, I'm not sure how critical frequency error is on things like...
I seem to get a lot of people sending me PM's to answer questions. I want to add a signature to request they don't do this, but ask in the forum instead. How can I do this? I'm sure it can be done, but I've looked all over my profile and can't find where I can add one.
Read the F***ing manual.
Seriously, it's pointless to ask questions like this, when if you spent a bit of time reading the manual, and doing a few of the examples, you would know the answers to these.
Those VNA prices are really excessive, though IF the calibration kit is well done, $700 is not that much. But that is a big IF.
For 3 GHz, a used HP 8753A, B or C would be a far better choice. To get to 6 GHz, you need an 8753B or later, with the 6 GHz option - but there are plenty of them on...
