ANADIGICS Announces New Patent Award.

Business Editors

WARREN, N.J.--(BUSINESS WIRE)--March 25, 2002

ANADIGICS, Inc. (Nasdaq: ANAD), a leading supplier of wireless and broadband communications solutions, has been awarded a patent for a low spurious signal DC-DC converter; US Patent No. 6314008.

The patented DC-DC converter provides very low distortion, i.e. a very low incidence of spurious signals, and a single power supply for front-end amplifiers used in equipment such as cable television systems and other broadband RF receivers.

"This new patent demonstrates, that ANADIGICS has assembled a world class research and development team that is committed to constantly pushing the boundaries of technology and developing cutting edge solutions for our customers," adds Dr. Charles Huang, Executive Vice President & Chief Technical Officer. "Since our first award in 1989, ANADIGICS has assembled a strong patent portfolio of 21 RF related patents issued and 17 pending. Not only are these patents a validation of our successful technical processes, but also proof that we are leading the marketplace in RF design and technology standards."

In amplifiers using depletion-mode devices such as Field Effect Transistors (FETs), there is a need for a bias voltage to turn the devices OFF (non-conducting) from a normally ON (conducting) state. If a depletion-mode device requires a negative bias supply, but the main circuit power supply is positive, then the negative bias potential must in some manner be generated from the positive potential. ANADIGICS' patented invention generates a plurality of output DC voltage levels with the opposite polarity of the DC control voltage. Additionally, it effectively converts the DC control voltage to an output voltage functioning as a dc-to-dc converter. The device may also be used as a balanced voltage source, which will only have spurious signals at even harmonics of the AC frequency signal. The device is suitable for use in microwave dc-dc converter circuits and as an adjustable low-spurious signal dc-dc converter that can be fabricated as a monolithic integrated circuit.

ANADIGICS (NASDAQ: ANAD) designs and manufactures radio frequency integrated circuit (RFIC) solutions for growing broadband and wireless communications markets. The Company's innovative high frequency RFICs enable manufacturers of communications equipment to enhance overall system performance while reducing manufacturing cost and time to market. By utilizing state-of-the-art manufacturing processes for its RFICs, ANADIGICS achieves the high-volume and cost-effective products required by leading companies in its targeted high-growth communications markets. ANADIGICS was the first GaAs IC manufacturer to receive ISO 9001 certification.
