Fully integrated millimeter-wave radio frequency system

An apparatus, comprising:

• a first interface for providing first intermediate frequency (IF) signals, a local oscillator (LO) signal, and control signals to a plurality of first RF modules;
• a second interface for providing at least second IF signals to a second RF module;
• and
• at least one processor configured to generate the LO signal, to generate the control signals, to generate the first IF signals to be provided to the first RF modules via the first interface and to generate the second IF signals to be provided to the second RF module via the second interface.

An apparatus, comprising:

• a plurality of first means for processing radio frequency (RF) signals, each first means for processing RF signals configured to receive RF signals to generate first intermediate frequency (IF) signals, wherein the plurality of first means for processing RF signals are coupled to each other via a first interface comprising transmission lines for carrying at least one of an IF signal, a local oscillator (LO) signal or a control signal;
• at least one second means for processing RF signals;
• and
• means for processing the first IF signals, wherein the means for processing the first IF signals is configured to provide at least one of the LO signal or the control signal to one of the first means for processing the RF signals via a second interface and to process one or more second IF signals received from the second means for processing the RF signals via a third interface.

An apparatus, comprising:
