IR transceiver slims down to fit latest PDAs
Agilent Technologies has announced a new serial infra-red (SIR) transceiver that is ideal for new-generation personal information devices, such as PDAs, which are becoming increasingly thinner.
The WS2512 operates in the UMTS2100 (1920 to 1980MHz) frequency range for CDMA and W-CDMA handsets.
UMTS2100 is a third-generation (3G) standard for regions of Europe and Asia that use GSM.
The WS2512 meets the stringent high-speed downlink packet access (HSDPA) linearity requirements for an output power of up to +27dBm.
In low-power mode in conjunction with a DC/DC convertor, performance is 13% at +7dBm output power with 8mA quiescent current.
The WS2411 operates in the UMTS1900 (1850-1910MHz) frequency range.
Used in the Americas and the Caribbean, it meets HSDPA linearity requirements for output power of up to +28.5dBm.
In low-power mode in conjunction with a DC/DC convertor, performance is 11% at +7dBm output power with 13mA quiescent current.
The WS2111 operates in the cellular band (824 to 849MHz) and meets HSDPA linearity requirements at output power levels up to 27.5dBm.
In low-power mode in conjunction with a DC/DC convertor, performance is 11% at +7dBm output power with 10mA quiescent current.
All versions of the CoolPAM W-CDMA product line can operate at 3.2 to 4.2V for compatibility with today's low-current consumption designs.
They all incorporate 50ohm input and output matching networks for simple integration, and are equipped with a control pin that sets operating parameters for highest efficiency when operating at low-output power levels.
The new PAs offer the lowest average operating current in the industry.
All versions are compatible with HSDPA, a packet-based data service providing data transmission at up to 10Mbit/s, and 20Mbit/s for MIMO (multiple-input multiple-output) systems over a 5MHz bandwidth.
The CoolPAM W-CDMA devices are supplied in a 4 x 4 x 1.4mm, 10-pin surface-mount module designed to assure high thermal conductivity, which minimises temperature rise for higher reliability.
All versions are fabricated with an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability and ruggedness.
Prototype quantities of the Agilent WS2512, WS2411 and WS1111 are shipping now through Agilent's direct sales channel.
Production volumes are expected by the third quarter of 2005. Request a free brochure from Avago Technologies ...
