NAME
FUNCTION
43
RFMIX_OUT-
RF Mixer Inverted Input (same as
RFMIX_OUT+
)
44
RFMIX_OUT+
Open Emitter Output of the RF Downconverter. This pin requires an external pull-down resistor of
1.2k
to establish the correct on-chip bias conditions. Requires a blocking capacitor.
45
VCC_RFMIX
Supply Voltage Pin for RF Downconverter. This pin requires external decoupling of typically
100pF.
46
RFMIX_IN
Input to RF Mixer. Requires a blocking capacitor that may be used as part of the match network.
48
LNA_OUT
LNA Output. Requires a pull-up inductor and a blocking capacitor. These may be configured as
the matching network.
