An Eight-element 6 to 18 GHz SiGe BiCMOS RFIC Phased-array Receiver

The University of California at San Diego (UCSD) recently developed a silicon RFIC covering the 6 to 18 GHz frequency range that is capable of controlling the phase and gain of eight elements in a phased-array receiver. The chip is only 2.3 x 2.4 mm, c...

Phased arrays allow the electronic steering of an antenna beam in any direction and with high antenna gain by controlling the phase at each antenna element. This beam steering technique is much more compact and much faster than mechanically steered arrays. Furthermore, phased arrays allow the creation of deep...
