2.4 - 2.5 GHz WLAN Chipset
The Waverider 2 series wireless local area network (WLAN) chipset operates in the 2.4 to 2.5 GHz ISM band and consists of a wireless data controller (model WL102B), 2.4 to 2.5 GHz RF and IF circuit (model WL600C) and 2.5 GHz frequency synthesizer (model WL800). The wireless data controller is designed to reduce the cost of radio data applications. The on-chip communication control block reduces software overhead and the protocol independent software can be used to support a variety of applications. The RF and IF circuit is a transmitter and receiver chip that is highly integrated to minimize external components. The device features low power consumption of 50 mA in transmit and 60 mA in receive functions. The frequency synthesizer handles 144 frequencies in 1 MHz steps when used with a 20 MHz crystal. The unit is serially programmed via a three-wire bus.

Fully Integrated RF Module
The Oncore series fully integrated RF module is designed for use in a wide range of GPS ap-plications, reducing potential layout, development and production problems associated with typical mixed analog-digital designs. The unit contains the entire RF section in one shielded and tested unit that provides the GPS downconversion function. The module includes an eight-pin connector for power, input and output, and a miniature MMCX RF connector for the antenna. Power (3 or 5 V) is provided by the host system via one of the pins. Size: 24 x 40 x 10 mm.
The model AD9283 8-bit analog-to-digital converter operates at 3 V, contains an on-board track-and-hold circuit and encode clock and, for many operations, requires no external references or driver components. The low power requirement (110 mW with an input frequency of 10.3 MHz at 100 Msps), single-supply operation and good dynamic performance make the unit suitable for use in battery-powered applications. The encoder input is TTL/CMOS compatible and the 8-bit digital outputs can be operated from a +3 V supply, allowing users the flexibility to interface with 2.5 V application-specific ICs. A power-down function can be used to bring total consumption down to 4.2 mW. The converter operates from -40° to +80°C and is available from stock in three speed grades of 50, 80 and 100 Msps. Price: $8.50 (1000) for the 100 Msps version.
