11 11—
High-Frequency LO Buffer Output. Open-collec-
tor output requires pull-up inductor or pull-up
resistor of 100Ω or less. Reactive match to the
load delivers maximum power.
LOHOUT11

FM Mixer Output. Requires a pull-up inductor to
V
CC
and a series capacitor as part of the match-
ing network.
FMOUT13
Low-Frequency LO Buffer Output. Open-collec-
tor output requires pull-up inductor or pull-up
resistor of 100Ω or less. Reactive match to the
load delivers maximum power.

Power Supply. Bypass with a 1000pF capacitor
as close to the pin as possible.

CDMA Mixer Differential Outputs. Require pull-
up inductors and series capacitors as part of the
matching network.

LO Output Buffer Enable. The LO buffers are
controlled separately from the rest of the IC. Drive
BUFFEN high to power up the LO output buffer
associated with the selected LO input port.
BUFFEN15
LO Doubler Logic Input. Drive LOX2 high to
enable the LO doubler.

Low-Band Mixer Input. Requires a blocking
capacitor and a matching network. The capaci-
tor may be used as part of the matching net-
work.

High-Band Mixer Input. Requires a blocking
capacitor and a matching network. The capaci-
tor may be used as part of the matching net-
work.
MIXINH20
Bias-Setting Resistor Connection. For nominal
bias, connect 20kΩ resistor to ground. The resis-
tor value controls the digital LNA’s linearity in
low-gain, digital, or FM mode, and controls the
mixers in all modes.

Slug SlugSlug
Ground Reference for RF, DC, and Logic Inputs.
Solder the slug evenly to the board ground
plane.

Mixer Differential Outputs. Require pull-up
inductors and series capacitors as part of the
matching network.
