More Information
Summary:This work presents a cellular transceiver capable of transmitting two simultaneous channels with an aggregate bandwidth of up to 40 MHz, supporting a 100 Mbps uplink rate. The transmitter has 8 RF output ports covering the cellular transmit bands within the 572-2100 MHz frequency range. It can support TX LTE-advanced Rel-12 Cat7, HSPA+ Rel-11, TDSCDMA Rel-9, and GSM/EDGE Rel-9. The 40 nm CMOS transmitter consumes 22 mA and 27 mA in 3G and LTE modes (at 0 dBm antenna power), respectively, including the PLL, DCXO and biasing for a single channel.
