An apparatus has an array of antennae. Each antenna in the array has a tile circuit including a frequency conversion circuit to generate from an incoming reference signal a local oscillator carrier signal operative as an outgoing reference signal for an adjacent tile circuit. A mixer receives the local oscillator carrier signal and combines it with an antenna signal to produce a frequency converted antenna signal. A matrix of phase shifters and variable gain elements produces a set of frequency converted and phase rotated antenna signals. Analog summers combine the frequency converted and phase rotated antenna signals with user input signals from the adjacent tile circuit for distributed analog beam forming of multiple streams. The user input signals correspond to distinct users tracked by the array of antennae.
