This general purpose board was created for high quality analog muxing/demuxing for demanding measurement applications.
Characteristics
- 256x100mm 8 layers PCB
- 8 <-> 1 channels
- 4 I/O per channels (ground commuted with the signal, so no common ground)
- Bandwidth : 0...200MHz (best use : 0...10MHz, see plot below)
- SMA or SMB connectors
- Signal relay based solution
- Balanced tree routage (same trace distance for any commuted channel)
- 50Ohms impedance controlled shielded coaxial traces
- 1x LED per channel (light when selected) + 1x power LED.
- 1x 2mm-pitched 2x6 connector.
Power supply / driving considerations
This board doesn't have any driving circuit on it.
One already existing driving board is MFSRELAYCTRL. Active channel can be manually switched too via an external box.
The following signals can be found on the connector :
