Abstract
A 94-GHz 4×4 phased array frontend capable of two-dimensional scanning with orthogonal polarizations for wireless communication and radar systems has been designed. The phased array frontend resolves the RF signal leakage and isolation dilemma encountered in typical systems employing a single antenna for both transmission and reception, effectively maximizing the system's dynamic range and linearity operation as well as minimizing the noise figure. Simulations at 94 GHz show high performance for the phased array frontend. In the receive (RX) mode, it has noise figure of 8.5/8.4dB at the radiating element, RMS phase error of 2.38/2.36° and gain error of 1.22/1.27dB, and total array gain of 17/22.3dB for H/V polarization, respectively, and ultra-high isolations from TX-Antenna (−200/−190dB), TX-RX (−106/−180dB) and V-H antenna ports (66/69dB). In the Transmit (TX) mode at 94 GHz, it achieves a radiated power of 7.8 dBm at the element antenna and RMS gain and phase errors of 1.28 dB and 2.19° at 94 GHz, respectively.
