Diodes adopt a smaller outline
Four high-performance diode chips are offered in the smallest surface-mount package ever.
Avago Technologies is now supplying four of its high-performance diode chips in the smallest surface-mount package that it has ever offered At only 1.2 x 0.8 x 0.6mm in height, 12 diodes could fit on a grain of rice

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).
The latest miniaturisations expand the company's offerings to developers of such diverse products as mobile handsets, radio frequency identification (RFID) tags, wireless local area networks, cable TV, and direct TV broadcast satellite systems.
The latest package helps Avago customers design in ever-smaller components in limited board spaces, allowing for creation of more competitively priced, compact, feature-rich wireless devices.
The package meets the European Union's Reduction of Hazardous Substances (RoHS) Directive requiring that manufacturers be responsible for eliminating products that contain six banned substances, including lead, beginning 1st July 2006.

Fibre Channel controller needs no memory
The HPFC-5400A Tachyon DX2 from Agilent Technologies is a 2Gbit/s dual-channel Fibre Channel controller that requires no external memory.
Each of the three Schottky-barrier diodes (HSMS-282Y, HSMS-285Y, HSMS-286Y) and the single PIN (positive-intrinsic-negative) switching diode (HSMP-389) is supplied in the low-cost industry-standard SOD-523 (small outline diode) package.
These products add to Avago Technologies' surface-mount diode family, which includes devices in such industry-standard packages as SOT-23, SOT-143, SOT-323, SOT-363, SOT-25 and SOD-323.
They are fabricated on 6-inch silicon wafers using Avago's proprietary diode processes.
"Our new SOD-523-packaged diodes demonstrate Avago's focus on miniaturisation with increasingly higher performance that continue to make our customers competitive worldwide", said Chee-Yong Saw, Worldwide Product Marketing Manager for Silicon Diode/RFIC Products in the Wireless Semiconductor Division at Avago Technologies.
The Avago HSMS-282Y Schottky-barrier diode is optimised for signal detection applications up to 4GHz and for mixing or frequency multiplying applications up to 6GHz.
It is an excellent choice as a detector and mixer for mobile handsets, wireless infrastructure, WLAN (wireless local-area network), WiMAX (IEEE802.16 broadband wireless access) and cordless phones, where low turn-on voltage and low resistance is most desirable.
This device features low turn-on voltage of 0.34V at 1mA and low dynamic resistance of 12ohm at 5mA).
The HSMS-285Y is a zero-bias detector diode optimised for use in small signal applications at frequencies below 1.5GHz.
It is particularly suitable for RFID tags where primary DC-biased power is not available.
It combines high-detection sensitivity (up to 50mV/uW at 915MHz) with low flicker noise (-162dBV/Hz at 100MHz).
The HSMS-286Y is optimised for use as a large-signal detector, as well as for modulating, signal converting and voltage doubling applications up to 6GHz, where large signal detection is most critical.
It provides the performance needed for applications including RFID and RF tag readers, and for DBS (direct broadcast satellite) LNBs (low noise block downconvertors).
It features high-detection sensitivity (50 mV/uW at 915MHz, 35mV/uW at 2.45GHz, 25mV/uW at 5.80GHz).
The HSMP-389Y is a PIN (positive-intrinsic-negative) diode optimised for switching applications up to 3GHz where low insertion loss, low series resistance at low current and low capacitance are required.
Applications range from wireless infrastructure and cable television (CATV), use as a DBS LNB multiswitch, and for switching in mobile handsets, cordless phones, and WLAN and WiMAX cards and access points.
The low insertion loss and series resistance is at 100MHz, typical RS of 3.8ohm at 1mA, 1.8ohm at 5mA, 1.5ohm at 10mA; low total capacitance is at 1MHz, a CT of 0.20pF typical with VR of 5V.
The HSMP-389Y also features a short carrier lifetime of 200ns at IF of 10mA and IR of 5mA.
All versions are available in 100-piece bulk packs and 3000 pieces on 7in tape-and-reel.
