Merged #1144 into master.
Stefan DK3SB, sent me this picture of his version of my frequency distribution amplifier. He modified the PCB to make it narrower (160mm), to fit a Hammond
1455R1601 enclosure (about 25 euros from Farnell).
Nice work! KiCad sources and gebers hopefully to follow, on ohwr.org
Update2: Here's the 14-hour data together with a 14-hour noise-floor run. The ADEV and TDEV results are more or less instrument-limited. Only for phase-noise above 100Hz offset is the instrument floor significantly below the result for the distribution amplifier.
Update: Here's a 14 hour run of the residual phase noise, ADEV, and TDEV, as measured through the frequency distribution amplifier. Instrument is a Microsemi 3120A phase-meter.
Aivon has now produced around 16 of these distribution amplifiers.
Update: Molex R/A 'long-neck' SMA-connector:
I sumbitted a few pull-requests to the KiCad libraries with some parts used on recent boards. Let's see if/when they make it into the main/released libraries...
On the to-do list is to submit an SFP-connector and Cage footprint... (unless someone has already done that?).
