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:

2. DWM-800B interfaces

2.1. 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:
