Sampling now, Nujira’s NCT-L1200 second-generation Coolteq.L envelope tracking chip debuts as the only product available supporting the maximum 20-MHz channel bandwidth of LTE. It is also scalable to support the future bandwidth expansions necessary for LTE-Advanced. According to the company, the chip meets stringent industry noise requirements and delivers significant advantages over comparable devices. These include the patented High Accuracy Tracking (HAT) architecture, which combines high-efficiency switch-mode power supply technology with high-bandwidth linear elements and is proven from power levels of 0.5W to 10 kW and beyond.
