UMTS/HSPA/GSM/GPRS/EDGE RF Transceiver LSI for Multimode/Multiband Communication MB86L01A

چکیده

We have developed RF transceiver LSI “MB86L01A,”which supports the GSM, GPRS, and EDGE communication methods for second-generation cell phones and the UMTS and HSPA communication methods for third-generation cell phones. It mounts a 3G DigRF interface on 1 chip. By adopting a low-noise circuit utilizing our rich digital circuit technology as a built-in circuit, it no longer requires the external parts which had previously been necessary, leading to a reduction in the number of external parts and contributing to cell phone thickness reduction and miniaturization.
