Advanced Filter Bank Analog and Digital Converter for All Digital Multiple Beam-Forming Array System

"This Small Business Innovation Research Phase I project demonstrates a breakthrough approach to very high-speed, high-resolution analog-to-digital conversion which improves the speed of conversion by up to six times the state-of-the-art by using a parallelarray of individual converters. The V-Corp Advanced Filter Bank Analog and Digital Converter (AFB ADC) technology will be integrated into a Harris Corporation advanced all-digital multiple beam array system for theater ballistic missile defense. The AFBADC architecture works because the filter bank signal processing significantly reduces the sensitivity to analog mismatches (e.g., phase distortion, clock skew, temperature drift) which prohibit existing parallel conversion methods (e.g.,Time-Interleaving) from achieving high resolution. V-Corp has proven the technical efficacy of the concept by successfully building prototype hardware with 12-bit resolution and 260 MHz sample rate (over twice as fast as state-of-the-art). Veryimportantly, the AFB ADC architecture will never become obsolete and will always exceed the state-of-the-art because it can easily be upgraded as new, more powerful ADC products become available. The architecture is amenable to single-chip integration forcompact, low-power applications. The AFB ADC technology enables an advanced all-digital shipboard array with multiple beams and a single aperture, steerable nulls to mitigate co-site interference and jamme
