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.

2.2.3. USIM interface
DWM-800B 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

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.

3.4. RF Exposure Compliance
The antenna(s) used for this transmitter must be installed to provide a separation distance of at least
20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or
Transmitter.
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: KA2WM800BA1”. The grantee's FCC ID can be used only when all FCC compliance requirements
are met.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module in the user’s manual of the end product which integrates this module.
15
The end user manual shall include all required regulatory information/warning as show in this manual.
