11:30 <bvernoux> Starlink dish teardown

11:30 <bvernoux> it is a massive antenna with tons of mini antennas forming a huge array ...

11:30 <bvernoux> Fun things is all chipset included are done by ST

14:50 <azonenberg> Well that's mildly annoying

14:50 <azonenberg> it seems like glscopeclient no longer runs on my waverunner

14:51 <azonenberg> GL_ARB_gpu_shader_int64 *is* supported on the Intel HD Graphics 530

14:51 <azonenberg> ... but only on Linux

14:51 <azonenberg> the windows driver doesn't seem to list it

15:36 <azonenberg> Also, i just discovered a new resistor i want to try on a probe

15:37 <azonenberg> The Vishay CH series. Flip chip but it comes with a 250 ohm option unlike the FC series

15:37 <azonenberg> And their 200 ohm has flatter frequency response than the FC series

15:39 <azonenberg> So basically it looks like if I switch from FC to CH series I could replace three (200-200-50) with two (250-200) resistors, greatly reducing the reflections between them

15:41 <azonenberg> it would also have slightly less peaking at high freqs: a FC0402 50 + 200 in series is 161 ohms at 10 GHz, a CH0402 250 is 172

15:42 <azonenberg> and for the second resistor, a FC0402 200 is 106 @ 10 GHz while a CH0402 200 is 157

15:42 <azonenberg> The price you pay for this is significantly increased cost (about $6 on digikey in low volume) as well as worse tolerances (2% vs 0.1% DC resistance)

15:42 <azonenberg> But i think for flatter RF performance it's worth it, i can easily calibrate out a small DC gain error

15:55 <_whitenotifier-f> [starshipraider] azonenberg adfb1cf - Finished AKL-PT2 layout changes for v0.4

15:56 <_whitenotifier-f> [starshipraider] azonenberg 77d3334 - Updated simulations for probes

16:10 <azonenberg> Just ordered the next rev AKL-PT2 (v0.4) with castellations on the tip plus soldermask on the main transmission line to reduce ENIG losses

16:10 <azonenberg> So we'll see how that works

18:24 <Bird|otherbox> bvernoux, yeah, I think each phased array element is like a 3 element Yagi made of patches

18:24 <Bird|otherbox> or at least 2 but 3 would make more sense I think if possible

18:25 <Bird|otherbox> the driven elements are on the outside of the board, the "floating" copper patches are an array of directors

18:25 <Bird|otherbox> and there might be an array of reflectors embedded inside the PCB itself on an inner layert

18:29 <Bird|otherbox> which is REALLY COOL if you ask me

18:30 <Bird|otherbox> because it's basically a 3D antenna array at that point, combining phased/driven array and parasitic array capabilities

18:42 <azonenberg> https://www.antikernel.net/temp/jitter-histogram.png

18:43 <azonenberg> You can now plot a histogram of TIE to get a plot of Tj in your signal

18:43 <azonenberg> so far no jitter decomposition
