ページを印刷するRF/LO Subsystem
At the RF input, parallel LC matching network was removed (never used on the original
LLRF4, layout considerations).
LO 1:8 power splitter (4 input mixers, 2 output mixers, power monitor, monitor connector)
is now built from 7 Mini-Circuits QCN-series quadrature splitters. These parts cover the
range from 220 MHz to 3.4 GHz in multiple bands.
The following parts can be used to populate the board according to the desired LO and
RF frequencies:
U13, U21, U22, U23, U24, U25, U26: 2-way LO splitter
220-470 MHz
330-580 MHz
425-675 MHz
450-750 MHz
800-1375 MHz
675-1300 MHz
1100-1925 MHz
1350-2450 MHz
1700-2700 MHz
2500-3400 MHz
M1, M2, M101, M102, M103, M104: level 13 mixer
40-2500 MHz
5-3000 MHz
RF down- and up-conversion can also be bypassed during production.
