ANALOG DEVICES AD6644/AD6624/AD6622/AD9754 SoftCell Multicarrier Transceiver Chipset Manual
User Manual
Analog Devices introduces the latest in Direct IF Sampling (DIFS) and Direct Digital Synthesis (DDS) technology to reduce the cost, size, and power of traditional multicarrier radios. Finally, the dynamic range barriers in converter technology have been overcome to permit an entire 25 MHz spectrum to be digitally processed. Incremental RF carriers are easily added (or reprogrammed) for most air interface standards.
