Abstract
A digital phased array antenna comprises a plurality of antenna elements, each element receiving an incoming signal. An analog-to-digital converter is coupled to at least one of the antenna elements to convert the incoming signal to a multi-bit digital signal. A demodulator or de-ramp circuit is coupled to the analog-to-digital converter to reduce the bandwidth of the multi-bit signal.
