For Immediate Release
Chelmsford, MA 08/10/2011 -
Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets has expanded its DC Power Management product line by introducing three new, complete monolithic Class-A amplifier biasing and monitoring solutions. The HMC980LP4E, HMC981 and HMC981LP3E are ideal for 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 the 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 HMC980LP4E, HMC981 and HMC981LP3E offer significant PCB area reduction by integrating negative voltage generator, automatic gate adjustment and power-up sequencing circuit blocks in a single monolithic device.
The HMC980LP4E targets amplifiers operating with bias currents up to 1.6 A and supply voltages from 5V to 16.5V. The device also features an optional current alarm feature, is available in a compact 4 x 4 mm plastic SMT package and requires a minimal number of external components.
The HMC981LP3E is a highly compact biasing solution that requires only eight standard external passive components and features simplified functionality compared with the previously released HMC920LP5E . Available in a 3 x 3 mm plastic SMT package, the HMC981LP3E is capable of biasing amplifiers with currents up to 200 mA and supply voltages from 4V to 12V. For customers designing with die amplifiers, the HMC981LP3E is also available in die format as the HMC981.
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.
