The size of DWM-800A 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-800A Figure 2-2 The rear view of DWM-800A 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-800A module provides an interface for RF antenna by Connector: DWM-800A 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.

Application note of DWM-800A interfaces DWM-800A provides rich interfaces for secondary development by the MINI PCI-E, such as USIM card interface, USB interface, UART interface, PCM（Pulse Code Modulation) interface, I2C interface, power supply interface and so on. The detailed information will be described in the following sections. 2.2.1. Power supply and Ground The power supply input for DWM-800A module is listed as follows: DC +3.3V～+3.6V, for DWM-800A working voltage; The description of DWM-800A Power supply and GND pins is shown in Table 2-1 below.

Table 2-2 DWM-800A USB interface description Signals of USB interface The correlative pins in MINI PCI-E SN. of MINI PCI-E Description DM USB_HS_DM 36 USB Data- DP USB_HS_DP 38 USB Data+ GND GND 4,9,15,18,21,26,27,29,34,35,37,43,50 GND 2.2.2.2. Reference circuit The reference circuit of USB interface is shown in Figure 2-5 below. 1) To get the reliable USB power supply, it is recommended to use a 10uF（C406) filter capacitor and a 22pF（C407) filter capacitor which need to be grounded. 2) To reduce the reflection caused by the high frequency alternating signal in the transmission, it is recommended to add a resistor with value below 10Ω to the DM and DP in USB interface to ensure correct transmission for USB data. Just like the resistors R408 and R409 in Figure 2-5. 3) To avoid static electricity in USB interface, it is recommended to use the ESD protection device. Just like the varistor RV406, RV407 and RV408 with capacitor values below 3pF. 4) To ensure USB working reliably, it is recommended to use additional protection device. Figure 2-5 The reference circuit of USB interface
9 2.2.3. USIM interface DWM-800A supports USIM card in UMTS mode as well as SIM card in GSM/GPRS/EDGE mode，and UIM card in WCDMA mode. 2.2.3.1. Description DWM-800A provides USIM card interface by MINI PCI-E which can be used in both UMTS and GSM/GPRS/EDGE networks. The Table 2-3 gives more detailed information. Table 2-3 DWM-800A USIM card interface description Signals offered by USIM interface The name of the correlative pins in MINI PCI-E SN. of the MINI PCI-E Description DATA USIM_DATA 10 USIM card data CLK USIM_CLK 12 USIM card CLK RST USIM_RESET 14 Reset signal VCC VREG_EXTUSIM 8 USIM card power GND GND 4,9,15,18,21,26,27,29,34,35,37,43,50 GND 2.2.3.2. Reference circuit The reference circuit of USIM interface is shown in Figure 2-6 below. 1) The DATA line of USIM is connected to SIM power supply by a pull-up resistor with reference value 15KΩ. 2) To avoid the instantaneous voltage overflowing, the resistor with reference value 22Ω can be used for the DATA, CLK and RST line. Just like the resistors R307, R308 and R309 in Figure 2-6. 3) To avoid the static electricity in USIM socket, it is recommended to use the ESD protection device for the DATA，CLK and VCC line. Just like the varistors RV301, RV302, RV303 and RV304 in Figure 2-6 this should be close to the USIM socket as possible. 4) To get more flat USIM power supply, it is recommended to use the filter capacitors. Just like C311 and C312 in Figure 2-6with reference value 33pF and 100nF. 5) To eliminate the peak interference and high frequency interference signal on RST and CLK line, the filter capacities (C310, C309) can be placed in RST and CLK line, the reference value is 33pF.

This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling: This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may bemaintained between the antenna and users. The final end product must be labeled in a visible area with the following: “Contains FCC ID: KA2WM800AA1”. The grantee's FCC ID can be used only when all FCC compliance requirements are met.
