-- Delivers Excellent Bias Stability over Supply, Temperature & Process Variations!

Hittite's High Current Active Bias Controller Now Available in Chip FormChelmsford, MA 05/03/2012 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has recently expanded its DC Power Conditioning product line. The new HMC980 is a High Current, Active Bias Controller die which is ideal for amplifier power management and control in cellular infrastructure, microwave and millimeterwave communications, fiber optic, consumer, military, space and test equipment applications.

Hittite's bias control solutions automatically adjust an amplifier’s gate voltage to achieve a constant bias current over part-to-part and temperature variations. This auto-gate bias adjustment provides a significant advantage compared with discrete-based solutions since it eliminates manual calibration. Additionally, the HMC980 Active Bias Controller die offers a significant PCB area reduction by integrating negative voltage generator, automatic gate adjustment and power-up sequencing circuit blocks in a single monolithic device.

The HMC980 is designed to control amplifiers operating in Class A mode with bias currents up to 1.6A and supply voltages from 5V to 16.5V. The HMC980 Active Bias Controller die occupies less than 3.2 mm2 of circuit area, requires a minimal number of external components, and incorporates an optional current alarm feature.
For applications which require a surface mount compatible solution, the HMC980 is also available in a 4 x 4 mm QFN plastic package as the HMC980LP4E. The HMC980 and the HMC980LP4E complement Hittite’s line of DC Power Management solutions which operate with bias currents up to 2A and supplies from 3V to 16.5V.

Die samples, SMT product samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company's e-commerce site or via direct purchase order. Released data sheets may be found at www.hittite.com.
