A Rel-12 2G/3G/LTE-advanced 3CC receiver

摘要

This work presents a cellular receiver capable of receiving three simultaneous channels with an aggregate bandwidth of 60 MHz, enabling a 300 Mbps downlink rate. The receiver has 16 RF LNA ports covering the cellular bands within the 572-2700 MHz frequency range. It supports LTE-advanced Rel-12 Cat6, HSPA+ Rel-11, TD-SCDMA Rel-9, and GSM/EDGE Rel-9. The 40 nm CMOS receiver consumes 13.7 mA and 17.6 mA of battery current in 3G and LTE modes, respectively, including the PLL, DCXO, and bia sing for a single channel.
