Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
Avago's CoolPAM power amplifiers provide the kind of extended "on" time that end users expect even as handsets begin to incorporate demanding functions such as TV viewing.
The reference design incorporates Avago Technologies' ACPM-7311 module for UMTS800 (Band 5, 824 to 849MHz), the ACPM-7331 module for UMTS1900 (Band 2, 1850 to 1910MHz) and the ACPM-7381 module for UMTS2100 (Band 1, 1920 to 1980MHz) operation.
CoolPAM technology significantly reduces battery power consumption, allowing mobile handsets to run cooler without the additional design time or expense of a DC/DC convertor.

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.
CoolPAM power amplifiers are already proven in handsets from leading manufacturers in Korea.
The reference design supports HSDPA (High Speed Downlink Packet Access) and W-CDMA (Wideband Code Division Multiple Access) UMTS (Universal Mobile Telecommunications System)/GSM (Global System for Mobile Communication)/GPRS (General Packet Radio Service)/Edge (Enhanced datarates for GSM Evolution) networks.
"Our highly efficient power amplifier modules allow manufacturers of handheld and portable devices to offer 3G features while significantly extending battery life", said Bryan Ingram, Vice President and General Manager of Avago Technologies' Wireless Semiconductor Division.
"With network upgrades to support advanced features such as HSDPA, subscribers are demanding multi-mode connectivity".
The CoolPAM W-CDMA devices are supplied in a 4 x 4 x 1.1mm, 10-pin surface-mount module designed to assure high thermal conductivity, which minimises temperature rise for higher reliability.
They are fabricated with an advanced InGaP (indium gallium phosphide) HBT (heterojunction bipolar transistor) MMIC technology offering state-of-the-art reliability, temperature stability and ruggedness.
The CoolPAM W-CDMA modules can operate at 3.2 to 4.2V for compatibility with today's low-current consumption designs.
They 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.
CoolPAM power amplifiers offer the lowest average operating current in the industry.
All versions are compatible with HSDPA.
The ACPM-7381, ACPM-7331 and ACPM-7311 CoolPAM power amplifier modules are sampling today.
