             ANADIGICS ANNOUNCES PRICING OF CONVERTIBLE SENIOR NOTES

WARREN, NJ--September 21, 2004--ANADIGICS, Inc. (Nasdaq: ANAD), today announced
that it has priced its offering of $33 million aggregate principal amount of
convertible senior notes due 2009, through an offering to qualified
institutional buyers under Rule 144A of the Securities Act of 1933, as amended.
These notes will be convertible at any time prior to maturity into shares of
ANADIGICS, Inc. common stock at a conversion rate of 200 shares of common stock
per $1,000 principal amount of notes, which is equivalent to a conversion price
of $5.00 per share and represents an approximately 29.53% premium to the closing
price of $3.86 per share of ANADIGICS, Inc. common stock on September 20, 2004.
The notes will bear interest at an annual rate of 5.00%, payable semi-annually
in arrears. The notes mature on October 15, 2009. ANADIGICS, Inc. has granted
the initial purchaser of the notes an option to acquire up to an additional $5
million aggregate principal amount of notes.

We expect to use the net proceeds of this offering to reduce our outstanding
indebtedness through the repurchase of at least $20.0 million aggregate
principal amount of our outstanding 5.00% convertible senior unsecured notes due
2006. Any remaining net proceeds not utilized to repurchase outstanding
indebtedness will be used for general corporate purposes.

This press release is neither an offer to sell nor the solicitation of an offer
to buy the notes or any other securities, and shall not constitute an offer,
solicitation, or sale in any jurisdiction in which such an offer, solicitation
or sale is unlawful.

The notes and the shares of common stock issuable upon conversion of the notes
have not been registered under the Securities Act of 1933, as amended, and may
not be offered or sold absent registration or an applicable exemption from the
registration requirements.
