PMB 8878

Product Summary

Infineon Technologies extend its well known X-GOLD baseband PMB 8878 to support the 3.5G mobile phone generation. The integrated dual-mode HSDPA/WCDMA/E-GPRS modem technology, together with high speed multimedia hardware accelerators and the advanced connectivity options enable PMB 8878 to fulfi ll the requirements of tomorrow mobile phones. INFINEON is one of the early platform vendors to support HSDPA category 8 (7.2Mbit/s). The implementation of equalizer based advanced receiver technology improves the data throughput, especially at high data rates, by up to 40%. In addition, the software programmable slot processing in the HSDPA Rx path provides further fl exibility for performance enhancements. The HSDPA performance of PMB 8878 meets and exceeds all test cases as specifi ed in the 3GPP standard. INFINEON 3.5 G physical layer architecture is future-proof and designed for an easy upgrade to higher HSDPA data rates, HSUPA and also Rx-diversity.
