Hittite's High Current Active Bias Controller Now Available in Chip Form
May 3, 2012 Press Release
-- Delivers Excellent Bias Stability over Supply, Temperature & Process Variations!
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
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.
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.
