Company Confidential 7.1 Quatech, Inc. AC Electrical Characteristics – Transmitter Transmit power is automatically managed by the device for minimum power consumption. The MAXIMUM transmit power at the RF connector is typically +15dBm ± 2 dB for B-Mode (all rates) and +12dBm+/-2dB for G-Mode (all rates). 7.2 Performance/Range The following table illustrates the typical data rates, performance and range the device is capable of providing using an omni directional antenna.
Company Confidential Quatech, Inc. 8.0 Antenna The unit supports antenna connection to two Hirose U.FL connectors, located on the top surface of the radio next to the RF shielding. The radio supports Rx diversity. Any antenna used with the system must be designed for operation within the 2.4GHz ISM band and specifically must support the 2.412GHz to 2.482GHz for 802.11b/g operation. They are required to have a VSWR of 2:1 maximum referenced to a 50ς system impedance. 8.
Company Confidential Quatech, Inc. TNC/SMA are not allowed (there are more that are not), RP-TNC/RP-SMA are allowed. 8.3 Host Chassis Mounted Antenna Host Chassis mounted antennas require no work on the host PCB. They utilize an antenna type called ‘flying lead’. There are two types of flying leads; one which provides a bulkhead mounted antenna connector and one which provides a bulk head mounted antenna. The type you choose will be determined by the application. A flying lead system connects a U.
Company Confidential Quatech, Inc. PCB Embedded – This approach embeds an antenna design into the host PCB. This approach is very common with add-in WiFi card (CF, PCMCIA, SDIO, etc.) as it requires no external connections and is the cheapest production approach. The lower production cost requires significant development cost and lack of performance and flexibility.
Company Confidential Quatech, Inc. Try to locate the antenna where there is a minimum of obstruction between the antenna and the location of the Access Points. Typically Access Points are located in the ceiling or high on walls. Keep the main antenna’s polarization vertical, or in-line with the antenna of the Access Points. 802.11 systems utilize vertical polarization and aligning both transmit and receive antenna maximizes the link quality. Utilize diversity where possible.
Company Confidential Quatech, Inc. contributes to the Equivalent Isotropically Radiated Power (EIRP) of the system. This is part of an overall measurement of the link quality called link margin. Link Margin provides a measure of all the parts of the RF path that impact the ability of two systems to communicate.

Company Confidential Quatech, Inc. 10.0 Drivers and Software Quatech supports its radios with a collection of drivers and tools. Driver supports OS’s which include WinXP, WinCE and Linux 2.6. These drivers are supplied with the radio in the development kit or can be obtained directly from Quatech Technical Support. A range of engineering tools are also available to assist in the integration of the radio into a system, evaluation of the radio for application suitability and regulatory testing.
Company Confidential Quatech, Inc. 11.0 Integration Guidelines The Airborne Performance Radio is designed for integration in to a wide range of advanced electronic systems and diverse applications, the success of the integration and final performance of the integrated system depends upon the integration process and hardware design, the following section provides a set of guidelines to optimize the integration of the radio.
Company Confidential Quatech, Inc. 11.4 Circuit Board Layout Guidelines When considering capacitance, calculations must consider all device loads and capacitances due to printed circuit board traces. Capacitance due to the traces depend on a number of factors, including the trace width, dielectric material from which the circuit board is made, and proximity to ground and power planes. The mating connector required on the host board is a DF12(4.0)-50DP-0.5, the manufacturer is Hirose. 11.
