genesis aligent
I have no experience with with MWO; I had used EESOF series IV back in the day and briefly used ADS. I've been using Genesys for almost 10 years.
Other than designing IC's -- I don't really see how Genesys is going to hold you back. I regularly design...
inductor selfmade
Well -- I was implying that you have a general idea of what the inductor value is (you can measure that) -- I often solder an inductor across a flange mount SMA connector (center pin to ground). Then you resonate this inductor with a very good capacitor. When it is...
how to test inductor
If you have a lab kit of capacitors that you know are likely to be way better than your coil (ATC A or B for instance), then I would make a parallel resonant circuit with your coil (to ground) in the band of interest and measure the resistance at resonance. Not perfect...
pll_filter
I'm guessing that this is the "additional" attenuation added by the 3rd pole (R1, C3 if I'm reading their schematic correctly) for reference spurs and such.
This is a bit of a dangerous parameter as you can request arbitrarily large attenuation that is not plausible (due to the...
You are right to hold the ground planes as sacred.
Assuming the current you're tying to pass is reasonable and your design rules allow it, I would recommend just routing a thin trace (5-10 mils) under a coupling cap or other series element in a non-critical area -- the lower the impedance the...
ground plane
I avoid power planes like the plague.
I see them like the ultimate low impedance transmission line -- once something gets on there, you really can't fight it. Of course, something *will* get on there. I don't mind bussing power around with wide strips, but always bring the...
deskcnc download demo -crack -torrent
Yeah, some of my "mentors" in this business used to call that stuff "methyl-ethyl-bad-s***". But boy did it work well.
I agree -- there are plenty of toxins around.
My office and lab are in my basement and I've been struggling with normal basement dust...
pcb microwave milling
eek, another RPI guy!
I agree-- nobody wants to be breathing in the dust. It seems though that most of the issue is, as your reference says, with irritation and the fact that there is dust, not that the dust itself is a toxin that reacts with the body. I would think...
large pcb milling machines
I recently upgraded to an accurate360 as well -- mainly to get video. I got the professional vacuum system as well. I think AccurateCNC is poised to make some real gains in this market over the competition.
Most of my prototyping is done on 9-10mil thick...
This is interesting -- I've not seen one with a series transformer before. Usually you just select the tap point (based on J.s. wong paper for instance). Using a transformer might give you a nice degree of freedom since the geometry of your resonator may actually keep you from tapping at the...
I looked into this myself within the last year. It was like pulling teeth finding some of the info.
I believe that there were certain waivers for equipment imported from the US and I do think that 900 MHz was generally allowed for ISM use.
You might check with the ITU website; I found a small...
Re: tuning of a filter
I suggest you dig up Milton Dishal's november 1951 IRE paper discussing the tuning
here's the reference:
M. Dishal, "Alignment and Adjustment of Synchronously Tuned Multiple Resonator-Circuit Filters" Proc. IRE 39, Nov. 1951, pp. 1448-1455
this is a classic.
