Ground for downconverter.
Must be connected to the system ground
with minimum inductance. Ground pat-
tern on the board should be formed as
wide as possible.
(Track length should be kept as short as
possible.)
Bypass of RF input for downconverter.
This pin is RF input for downconverter
designed as double balanced mixer.
This high-impedance input should be
matched with external chip inductor. (eg
4.7 nH).
Open emitter pin of low noise amplifier.
Grounded with capacitor (eg 3 pF) and
register (eg 22
This pin can control downconverter’s
ON/OFF operation with bias as follows;
This pin can control upconverter’s ON/
OFF operation with bias as follows;
Supply voltage for upconverter.
Must be connected bypass capacitor
(e.g 1 000 pF) to minimize ground im-
pedance.
