ADC12Dxx00RF Direct RF-Sampling ADC Overview - Revolutionize Radio Architectures

DR Scott introduces National's 12-bit direct RF-sampling ADCs can directly sample input frequencies up to and beyond 2.7 GHz at up to 3.6 GSPS. A single direct RF-sampling ADC can replace an entire IF-sampling or ZIF-sampling radio signal path subsystem of mixers, LO synthesizers, amplifiers, filters, and ADCs, drastically reducing bill of materials (BOM) cost, design time, and board size, weight, and power.
