Name

Description

Connection

1

VAGC

AGC filter capacitor

Single capacitor (10nF) to GND

2

ANT_BIAS

External antenna bias output

Connect to external antenna on ANT1_IN (pin

3). Use capacitor to DC block the bias from the

ANT1_IN input.

3

ANT1_IN

RF input from external antenna

DC bias on this pin. DC blocking capacitor

required. Connect to RF input matching network

4

LNA_IN

RF input, via on-chip LNA

DC bias on this pin. Connect either direct to

passive GNSS antenna element, or to grounded

components using a DC blocking capacitor.

5

RX_EN

Receiver enable

Connect to VDDN to enable radio

Connect to VSSN / GND to disable radio

6

VCC_LNA

Analogue power supply for LNA

Connect to VCC via dedicated decoupling

network to enable LNA

Connect to GND to disable LNA

7

ANT_SW_OUT

Antenna switch output

DC bias on this pin. Connect to SAW filter input

or coupling capacitor.
