3.2 Connectors

3.2.1 Module Signal and RF Connectors

The LTE-NAD has 172 signal pins (2xAA and 2xBB) connector pads with 1.0mm pitch. The signal pads

are located close to the board edges.

There are three antenna pads, each collocated by RF GND connectors

- Main transmit and receive antenna – pin LGA_PRX_ANT

- Diversity antenna for WCDMA respective MIMO antenna for LTE – pin LGA_DRX_ANT_IN

- GNSS antenna for both GPS and GLONASS – pin LGA_GPS_DRX_ANT

3.2.2 Ground and Heat Dissipation Connectors

To support the usage of module under complicated thermal conditions, there are a number of large

grounded pads in the center of PCB. These pads are dedicated ground pads to transfer heat dissipation

to a carrier board.

This should be especially considered by customer designs. A reference design showing landing patterns

and PCB stack-up is available on request.

3.3 Main Interfaces

3.3.1 USB

The NAD has one USB2.0 OTG high speed (480MBit) compliant interface including the PHY. The IF

consists of 5 signals:
