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:
