Pin No.

Name

Description

Connection

8

ANT_DET

External-antenna connected

detect output (controls internal

antenna switch

)

Logic 1 output (VDDN) = External active

antenna connected. Antenna switch routes the

ANT1_IN (pin 3) signal to ANT_SW_OUT (pin

7).

Logic 0 output (VSSN) = No external active

antenna connected. Antenna switch routes the

LNA_IN (pin 4) signal to ANT_SW_OUT (pin 7).

Antenna switch can be overridden by driving this

pin from a DC source (<10kΩ impedance)

9
