ANADIGICS Expands Intellectual Property Portfolio; ANADIGICS Granted Five New Patents for Innovations in RFIC Design
WARREN, N.J. -- April 5, 2006 -- ANADIGICS, Inc., a leading supplier of wireless and broadband solutions, today announced five new patents covering innovations in the design and development of radio frequency integrated circuits (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 Vice President and Chief Technical Officer 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 describes 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 was granted for efficiency enhancements for power amplifiers through the use of uniquely designed biasing circuits and combined heterojunction bipolar transistor (HBT) and field-effect transistor (FET) processes.
Patent 6,998,920 covers the 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 discloses 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 was granted for fabricated GaAs bipolar and FET structures on the same die. This patent is being used in ANADIGICS' industry-leading InGaP-Plus(TM) technology, allowing for higher levels of integration and performance.
