Abstract
A phased array mm-wave device includes a substrate, a mm-wave transmitter integrated onto the substrate configured to transmit a mm-wave signal and/or a mm-wave receiver integrated onto the substrate and configured to receive a mm-wave signal. The mm-wave device also includes a phased array antenna system integrated onto the substrate and including two or more antenna elements. The phased array mm-wave device also includes one or more dielectric lenses. A distributed mm-wave distributed combining tree circuit includes at least two pairs of differential transconductors with regenerative degeneration and accepts at least two differential input signals. Two mm-wave loopback methods measure the phased array antenna patterns and the performance of an integrated receiver transmitter system.
