LO power budget/ cable plant 33 dbm max amp output 29.5dbm after splitter 7m of LDF4-50 cable = 1.4 db plus 0.25 db per connector=1.9db loss 27.6dbm 26.88dbm 13.5m of LDF4-50 cable = 2.71 db plus 0.25 db per connector=3.25db loss 23.63dbm 20.13dbm after splitter 20m of LDF4-50 cable = 4 db plus 0.25 db per connector=4.5db loss dbm 1db loss in these cables 17.6dbm 26.88dbm 16.6dbm 27.6dbm 16.6dbm 10m of LDF4-50 cable = 2db plus 0.25 db per connector=2.5db loss 24.3dbm All 8 way splitters have 10db loss All cables from 8 way to down mix boxes should have no more than 2db loss These cables should be made from LDF db/meter

Some where in this location is an ideal location for QBPM electronics 42 db gain 33dbm amp with 2way splitter 8 way splitters 10db directional couplers 2 way 3 db splitter LDF4-50 cable or equivalent LDF2-50 cable

8 way splitter LDF4-50 cable or equivalent 6 way splitter LDF2-50 cable

8 way splitters LDF4-50 cable or equivalent LDF2-50 cable Some where in this location is an ideal location for QBPM electronics

Downmix boxes Downmix boxes and hybrids to be mounted on to the steel plate fixed to the side of the concrete magnet supports Downmix boxes to be on 25mm standoffs (SLAC supplied) Hybrid Downmix box standoffs

Put a connector on the drain wire as shown for grounding the connector shell if needed DC Power Distribution
