apply DC to these pins

7, 11, 24, 30,

31, 32, 34, 49,

52, 54, 55, 62

No Connection. Not internally connected. OK to connect to VCC,

OK to connect to GND

TDD_A

Standby control for Channel A. Includes an internal pull-up

resistor so leave as NC for Standby mode. Set this pin to low or

GND for normal operation.

LCmode

Low_Current Mode. Includes an internal pull-up resistor so leave

as NC for LC mode. Set this pin to low or GND for STD mode.

TDD_B

Standby control for Channel B. Includes an internal pull-up

resistor so leave as NC for Standby mode. Set this pin to low or

GND for normal operation.

RFIN_B

Diversity Channel RF Input. Internally matched to 50Ω

Parallel Gain Control Input

– MSB. Includes an internal pull-up

resistor.

Parallel Gain Control Input. Includes an internal pull-up resistor.

Parallel Gain Control Input

– LSB (1 dB step). Includes an

internal pull-up resistor.

ISET_B

ChB VGA Icc set: Recommended resistor value = 3.83K

IFOUT_B+

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

inductor

IFOUT_B-

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

inductor

MX_IF_BiasB

Connect the specified resistor for either Standard mode (41ohm)

or LC mode (62ohm) from this pin to ground to set the bias for the

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

MX_IFB+

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

inductor from this pin to VCC.

MX_IFB-

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

inductor from this pin to VCC.
