LNA Bias-Setting Resistor Connection. For nominal bias,
connect a 20k
Ω resistor to ground. The resistor value
controls the LNA’s linearity in high-gain, high-linearity
modes.
RLNA 3
Low-Band LNA Output. Connect a pull-up inductor to
V
CC and an external series capacitor as part of the
matching network.
LNAOUTL 2
High-Band LNA Output. Connect a pull-up inductor to
V
CC and an external series capacitor as part of the
matching network.

trol modes.
SHDN —
Low-Band RF Input. Requires a blocking capacitor and a
matching network. The capacitor may be used as part of
the matching network.
LNAINL 5
High-Band RF Input. Requires a blocking capacitor and
a matching network. The capacitor may be used as part
of the matching network.

High-Frequency LO Input. For MAX2321, used in cellular
digital mode and in PCS mode with the doubler active.
For MAX2320/MAX2327, used in PCS mode without the
doubler. For MAX2322, used with or without the doubler.
For MAX2326, used in PCS mode and cellular digital
mode with the divide-by-two.
