Pin No.

Mnemonic

Description

27, 31

VPLO

Power Supply Connections for the LO Path. Decouple the VPLO pin with 100 pF and 0.1 µF capacitors as close

as possible to the pin.

28, 30

LOIN, LOIP

LO Inputs. These inputs are 100 Ω differential inputs for the LO path. The LO input frequency range is 5.4 GHz

to 14 GHz. The on-chip LO frequency doubler can be enabled via a SPI command.

32

ALM

Alarm. The ALM pin indicates internal alarm conditions. The ALM pin is logic low when an alarm condition is

detected.

EP

Exposed Pad. Solder the exposed pad to a low impedance ground plane.
