Revision History

1. Overview

1.1 Purpose

This document defines requirements for integrating the surface mount Garmin A03302 2-way satellite transceiver
module with a host design.

1.2 Introduction

The A03302 module is a standalone 2-way satellite communication short burst data transceiver solution.

The module is designed as a surface mount, package-on-package (POP) PCB; requiring a mating area on the host
PCB of approximately 31mm X 38mm.

A host processor is required to interface to the module via UART. The module includes a GPS pass-through
option, allowing for a single antenna solution for both GNSS and satellite communication. If this option is not
used, the GPS_LNA_OUT pin must be properly terminated. A 49.9Ω 1% resistor can be used.

1.3 Dimensions

The following section shows mechanical drawings and dimensions.

Care must be taken to prevent shorts between exposed test points of the module and the host PCB.
