Infineon Ships One Billion RF-Transceivers; Introduces Next-Generation LTE Chip

Neubiberg, Germany, November 20, 2007 – Infineon Technologies AG (FSE/ NYSE: IFX), a leading supplier of communication ICs, today announced it has shipped its one billionth RF transceiver. With more than 230 million handset transceivers shipped in 2006, Infineon holds the leading market share in a total addressable market of just over one billion units, reports the market research company Strategy Analytics. Infineon is shipping its communication ICs for more than 15 years to all major companies in the mobile phone segment, including Nokia, Samsung, Motorola, Sony Ericsson and LG.

„We produce seven RF transceivers every second and approximately every fourth mobile phone worldwide has Infineons RF transceiver technology integrated”, stated Stefan Wolff, vice president, Communication Solutions business group and general manager of the RF Engine business unit at Infineon. “Our strong footprint in the market is an indicator of our competitiveness and our best-in-class quality of products and innovative development skills of our engineers.”

The newest member in the Infineon family is the SMARTi® LTE, the world’s first highly integrated long-term-evolution (LTE) RF transceiver. The SMARTi LTE is the world’s first RF transceiver supporting LTE functionality in a single-chip RF silicon processed in CMOS, measuring just 5 x 5 mm in a WFSGA-81 package. Infineon’s LTE transceiver provides outstanding RF performance to enable handset manufacturers the ability to provide high data rate up- & downlink connections for upcoming LTE network field trials. Covering the entire spectrum of allocated LTE RF bands (Band I to X) and providing switchable baseband filtering (up to 5, 10, 20 MHz) Infineons SMARTi LTE fits global RF requirements and band combinations.

With the SMARTi LTE, Infineon has again demonstrated its leadership for next-generation wireless standards. The new RF transceiver provides excellent error vector magnitude (EVM) and low-power consumption for LTE applications.

Silicon has been provided to selected customers. Volume shipments are expected to be available by 2010.
