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.
Analog Devices introduces the SoftCell Multicarrier Transceiver Chipset, which utilizes Direct IF Sampling (DIFS) and Direct Digital Synthesis (DDS) technology to reduce the cost, size, and power of traditional multicarrier radios. This chipset is designed to enable next-generation software-based stations by consolidating RF channels within a single ADC and replacing expensive analog tuners and filters with digital signal processors.
