1. Introduction

1.1. Overview

The DC-HSPA+ Mini PCIe module DWM-800B , powered by MT6280 chipset, can be integrated into any devices
for 3G mobile applications. It provides SMS, MMS, Call as well as high speed internet access to DC-HSPA+and
UMTS networks worldwide. Main features of DWM-800B is listed in table 1-1

Table 1-1 Main Features of DWM-800B

1.2. Application Type

The application type of the module is shown as bellow:

All instructions relating to the integration of the module described on the FCC Grant notes must be followed.

1.3. Installation Guidelines

Careful planning and preparation of any installation will always benefit the end result, always read and follow all installation
instructions. Follow ESD precautions and prepare an SD safe workspace for installation. Turn the power to the host off and ground
yourself to dissipate static charge.

Mount only in sockets and locations intended for Mini PCIe cards consult manufacturer on thermal management
recommendations for the module mounted within the host.

1.4. Application scenario

The HSPA module DWM-800B supports Voice Call, SMS, MMS and internet access functions. The block diagram of
DWM-800B is as follows:

DWM-800B interface summary

The module DWM-800B supports multimode operation: DC-HSPA+, UMTS (850/1900/2100 MHz) and quad-band
GSM (850/900/1800/1900 MHz). The size of DWM-800B is 51mm*30mm*4.7mm. The appearance is shown in Figure
2-1 and Figure 2-2.

Figure 2-1 The front view of DWM-800B Figure 2-2 The rear view of DWM-800B

The MINI PCI-E is shown as in Figure , which is the main interface for application. RF antenna pad connector is

shown as in Figure 2-1 .

2.1.1. RF interface

The DWM-800B module provides an interface for RF antenna by Connector: DWM-800B uses HRS’s U.FL-R-SMT
RF connector on the rear side.

Solder pad mode: The antenna can also be soldered to the pad on the module which has a ground pad close to the
antenna pad.

The ground impedance of RF antenna is 50Ω. The RF connector is shown in Figure 2-3.

Figure 2-3 The sketch map of RF connector

It’s required to use RF cable of which the insertion loss should comply with:

• GSM850/900<1dB

• DCS1800/PCS1900<1.5dB

• UMTS2100/ UMTS1900/ UMTS850<1.5Db

There are two RF connectors in DWM-800B ,the description of them is shown in Figure 2-4 below:
