Microsemi Features Breakthrough Package in New High Volume RF PIN Diodes Line

Targets WiMAX and WLAN Applications


IRVINE, Calif., May 31, 2007 (PRIME NEWSWIRE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog and mixed signal integrated circuits and high reliability semiconductors, has announced a new line of RF PIN diodes in a breakthrough surface mount package for high volume microwave applications including attenuators and antenna switching in WiMAX and wireless LAN systems.

With superior electrical and thermal performance compared to standard plastic packaging, Microsemi's new series of GigaMite(tm) PIN diodes can deliver higher frequency coverage and better power handling than is found in conventional RF diodes.

Low package parasitics provide a smooth non-resonant functionality through the 5 GHz broadband range. High quality dielectric materials result in low loss and support broadband performance.

"We see our new GigaMite line as a way to provide commercial customers with performance that's near what Microsemi delivers to our high-rel customers in the defense and aerospace markets," said John Caruso, Vice President and General Manager of Microsemi's Microwave Products operation in Lowell, Massachusetts.

First devices in the new GigaMite series are designated GMP4201 through GMP4232 with voltages ranging from 75V to 300V. The package measures only 0.052 x 0.072 inch, the identical footprint of conventional SOD 323 packaging. Its height is only 0.035 inch. All GigaMite devices are RoHS Compliant and have an MSL 1 Classification.

Technical information on the GigaMite RF diodes is available on the Microsemi website, http://www.microsemi.com. Immediate sampling can be ordered through this site, or from Microsemi sales representatives and authorized distributors. Unit price in 1M lot quantities is $0.40.
