PIN DESCRIPTION (CONTINUED)

LO1_ADJ

Connect the specified resistor for either Standard mode (91

Ω ) or

LC mode (180

Ω ) from this pin to ground to set the LO common

buffer Icc.

LO_IN

Local Oscillator Input. Connect the LO to this port through the

recommended coupling capacitor.

LO_IN_RTN

Transformer ground return. Ground this pin close to the device

LO2_ADJ

Connect the specified resistor for either Standard mode (1.21k

Ω)

or LC mode (1.91k

Ω) from this pin to ground to set the LO drive

buffers Icc.

MX_IFA-

Diversity Mixer Differential IF (-) Output. Connect a pullup

inductor from this pin to VCC.

MX_IFA+

Diversity Mixer Differential IF (+) Output. Connect a pullup

inductor from this pin to VCC.

MX_IF_BiasA

Connect the specified resistor for either Standard mode (40.2

Ω )

or LC mode (62

Ω) from this pin to ground to set the bias for the

Diversity IF amplifier. This is NOT a current set resistor.

IFOUT_A-

Channel A Differential Output -. Pull up to Vcc through an

inductor

IFOUT_A+

Channel A Differential Output +. Pull up to Vcc through an

inductor

ISET_A

ChA VGA Icc set: Recommended resistor value = 3.48k

Parallel Gain Control Input – LSB (1dB step)

Parallel Gain Control Input

Parallel Gain Control Input - MSB

Exposed Pad. Internally connected to GND. Solder this exposed

pad to a PCB pad that uses multiple ground vias to provide heat

transfer out of the device into the PCB ground planes. These

multiple via grounds are also required to achieve the noted RF

performance.
