| Popis: | Carrier aggregation is a key feature of the 3GPP LTE-Advanced cellular network standard that combines multiple channels to support higher data rates and improve the utilization of fragmented spectrum holdings. This work presents a cellular transmitter capable of transmitting a maximum of four channels simultaneously, two contiguous channels in two bands, with an aggregate bandwidth of up to 80 MHz, supporting a 200 Mbps uplink rate. The transmitter has 8 RF output ports covering the cellular transmit bands within the 572–2025 MHz frequency range. It can support LTE-Advanced Release 12 Cat7, $\text{HSPA} + \text{Release} 11$ , TDSCDMA Release 9, and GSM/EDGE Release 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. |
