Abstract
Embodiments are directed to operating an analog signal processing circuit to emulate a Rotman lens. The analog signal processing circuit applies a plurality of time delays to a plurality of signals associated with a plurality of beam ports. The analog signal processing circuit forms a plurality of output beams for transmission by a plurality of array ports included in an array based on the time delayed signals by summing the time delayed signals. The time delays are based on a direction of transmission of the output beams.
