Anadigics expands its IP portfolio

ANADIGICS, Inc., announced no less than five new patents covering innovations in the design and development of RFICs. The patents strengthen the Company's impressive intellectual property portfolio and extend its technological advantages across its wireless and broadband product families.

“We continue to leverage our expertise in RFIC design to supply innovations which will power the next generation of wireless and broadband devices,” said Dr. Charles Huang, Executive VP and CTO at ANADIGICS. “ANADIGICS continues to invest in extending our technology leadership and building our strong intellectual property portfolio, which is the driving force behind many of our differentiated solutions.”

- Patent 6,937,102: a new method for low bias current/temperature compensation current mirror in linear power amplifiers. The design increases the power efficiency of the overall circuit and includes a temperature compensation circuit to adjust the bias of the amplifier, to stabilize the performance in a wide temperature range.

- Patent 6,970,039: efficiency enhancements for power amplifiers through the use of uniquely designed biasing circuits and combined HBT and FET processes.

- Patent 6,998,920: monolithically fabricated HBT amplification stage with a current-limiting FET. The FET structure provides improved ruggedness by limiting the base or collector current to the HBT during severe load mismatch and/or high overdrive.

- Patent 7,009,454: a new method for optimizing an amplifier with an adjustable output range. This circuit provides excellent energy efficiency at many power levels by using resonant components to provide consistent operating parameters over a wide range of power levels.

- Patent 7,015,519: fabricated GaAs bipolar and FET structures on the same die. This patent is being used in ANADIGICS’ industry-leading InGaP-Plus™ technology, allowing for higher levels of integration and performance.

Last week, ANADIGICS, Inc., said it had completed an underwritten public offering of an aggregate of 10,446,200 shares of its com-mon stock, comprising the sale of 9,200,000 shares on March 15, 2006 and the issuance of an additional 1,246,200 shares upon the exercise by the underwriters of their option to purchase additional shares to cover overallotments. After deductions, it received approximately $53.4 m in aggregate net proceeds, which it will use to repay at maturity the noteholders of its outstanding $46.7 m aggregate principal amount of 5% Convertible Senior Notes due on November 16, 2006 and the remainder for general corporate purposes, including capital expenditures.

EDITORIAL COMMENT: As with other news this week patents are making the headlines. In this instance the situation pertains to the RF microelectronics side of the business. Similarly, these companies have moved up in importance anything relating to intellectual property. Nowadays most engineers are prevailed upon by management to encaspulate as much of their work as possible in new patent applications. This is despite patent creation being a fairly intensive activity in terms of time and money. Interestingly, Anadigics likes to announce multiple patent awards saving them up to announce in between stock and product launch announcements. The last time it reported such news was last August when it also scored five new patents. Gaining patent awards is regarded as essential in today's competitive business environment. IP is closely linked with perception of company valuations and therefore has even closer links with the performance of the company in the stockmarket such as in the defence and expansion of its market presence.
