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

FM Mixer Output. Requires a pull-up inductor to
VCC and a series capacitor as part of the match-
ing network.

Low-Frequency LO Buffer Output. Open-collec-
tor output requires pull-up inductor or pull-up
resistor of 100

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.

Bias-Setting Resistor Connection. For nominal
bias, connect 20k
Ω 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.
