2019-01 Sync Technology - planning commercial production of PDA/FDA
Sync Technology from China has plans to produce the PDA/FDA http://www.synctechnology.cn/EN_detaile.aspx?id=153
1-to-8 Pulse and Frequency Distribution Amplifier
2018-12 FDA performace testing
14-hour runs on FDA S/N 16 from Aivon LTD now in Aders’ blog:

The conclusion is that it is quite hard to measure the performance of
the amplifier, because the instrument noise-floor usually dominates!
1-to-8 Pulse and Frequency Distribution Amplifier
2018-12 Narrow version of FDA-board
Here’s a modification of the FDA PCB design to fit in an enclosure that
takes a 160mm wide board:

WRS Fan-less hardware
Over 100 WRS-FL produced!
Over 100 WRS-FL has been produced, many of them will be installed at Daocheng, The LHAASO site.
RF Multiplexer 8ch 1GHz
2018.11 design update
migrate to kicad5 symbols and footprints. only minor changes to pcb-design. new PDF hardcopies of 2018.11 PCB, SCH, and BOM.
Radiation Tolerant LED Luminaire
New schematics added
For those who can’t or do not wish to download LTSpice to review the project schematics and simulations, we have now made available all 3 design variants in PDF form, so that they can be more easily viewed on any computer. A detailed BOM is also available for Variant 3.
White Rabbit
15-11-2018: EC Webinar 5 Dec: OSHW for science & beyond...
Webinar: How to foster open source hardware for science and beyond: the WR project
Javier Serrano (CERN) and the Open Science Monitor Consortium will share the lessons learnt from White Rabbit case and discuss on how to foster open source scientific hardware in Europe.
RF Multiplexer 8ch 1GHz
2018 September: Arduino MKR Zero controller and revised PCB
Revised PCB with 10-pin IDC/ribbon-cable for powersupplies and SPI-control. Control by Arduino MKR Zero with Ethernet shield. This arduino will be easier to integrate into a 1U enclosure, and removing the voltage-regulators for the mux-PCB simplifies the board.
WRS Fan-less hardware
WRS-FL V1.2 Reviewed by LHAASO projected.
Due to the harsh environment of LHAASO project, we redesign the WR switch to improve the heat dissipation thus avoid the necessary of the fan. After several months of development and testing, 50 WRS-FL has been produced.
