Chapter 1 Functional Description
We are appreciated that your purchasing this IEEE802.11b/g Mini PCI WLAN
Module. This product provides the easiest way to wireless networking.
This User Manual contains instructions in the operation of this product.
Please keep this manual for future reference.
1.1 Features
Includes Encore signal processing for Industry-leading receive sensitivity and
extended range:
․ -71 dBm at 54Mbps
High level of integration with direct conversion radio architecture
Flexible support for a variety of system bus interfaces including: PCI, Mini
PCI, CardBus, PCMCIA.
Programmable data rates of 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, and 54 Mbps.
Hardware-based IEEE 802.11i encryption/decryption engine, including
64-bit/128-bit WEP, TKIP, and AES
IEEE802.1x support.
Dynamic Power Management under driver control.
WHQL-certified drivers for Windows® XP/Me/2000/98SE/98 operating
systems.
Wi-Fi® compliant.
1.2 Integrated Radio Transceiver
This Mini PCI module includes an integrated RF transceiver that has been
optimized for use in 2.4-GHz WLAN systems. It has been designed to provide low-
power, low-cost, and robust communications for applications operating in the
globally available 2.4-GHz unlicensed ISM band. With an external transmit power
amplifier, it develops full output power per the IEEE802.11b/g Specification.
1.3 Receiver Path
This Mini PCI module has a wide dynamic range, direct conversion receiver. It
employs high-order on-chip channel filtering to ensure reliable operation in the
noisy 2.4-GHz ISM band. The excellent noise figure of the receiver makes an
external LNA unnecessary.
1.4 Transmitter Path
This Mini PCI module includes a linear transmitter capable of delivering up to +15
dBm while meeting the IEEE802.11g specification. The output power is adjustable
in 1-dB steps, down to 0 dBm. Base-band data is up-converted directly to the 2.4-
GHz ISM band.
1.5 Calibration
This Mini PCI module enables the device to be used in high-volume applications
because calibration routines are not required during manufacturing test. These
calibration routines are performed periodically in the course of normal radio
operation.

Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.
This device and its antenna(s) 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:
OEM integrator is still responsible for testing their end product for any additional compliance
requirements required with this module installed (for example, digital device emissions, PC
peripheral requirements, etc.).
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.
Without Co-located
The antenna(s) used for this transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter. And the antenna has to be installed that 20cm can be maintained
between the antenna and the user.
Labeling Requirement for OEM Integrator
The final end product must be labeled in a visible area with the following: "Contains TX FCC ID:
TX2-RTL8185".
For Canada
"The installer of this radio equipment must ensure that the antenna is located or pointed such that
it does not emit RF field in excess of Health Canada limits for the general population; consult
Safety Code 6, obtainable from Health Canada’s website www.hc-sc.gc.ca/rpb"
