Bidirectional image-rejection active array with reduced LO requirement

A radio frequency (RF) frontend integrated circuit (IC) device, comprising:

• one or more RF transceivers to transmit and receive RF signals within a first frequency band and RF signals within a second frequency band that is higher than the first frequency band;
• a bidirectional local oscillator (LO) signal generation circuit coupled to the one or more transceivers to generate a bidirectional LO signal, wherein the bidirectional LO signal is injected between the first frequency band and the second frequency band, and wherein the bidirectional LO signal generation circuit is to perform a high-side LO injection for the RF signals within the first frequency band by injecting the bidirectional LO signal having an LO frequency higher than the first frequency band and to perform a low-side LO injection for the RF signals within the second frequency band by injecting the bidirectional LO signal having the LO frequency lower than the second frequency band;
• a multi-channel transmit (TX)/receive (RX) power splitting/combing circuit coupled to the one or more RF transceivers;
• a wideband in-phase and quadrature (I/Q) LO generation circuit coupled to the bidirectional LO signal generation circuit;
• a TX up-conversion circuit coupled to the wideband I/Q LO generation circuit;
• and
• a RX down-conversion circuit coupled to the wideband I/Q LO generation circuit.
