Each of the four phased-array ICs in a tile integrates 32 receive and 16 transmit elements with dual outputs to support 16 dual polarized antennas. Multiple operating modes are supported, including the simultaneous reception of horizontal and vertical polarizations. Fabricated using an advanced IBM SiGe semiconductor process, the ICs also integrate frequency synthesis and conversion as well as digital control functions.The complete scalable solution, which includes antennas, packaging, and transceiver ICs, transforms signals between millimeter-wave and baseband, all in a form factor smaller than an American nickel.
