abstract

  • 2015 IEEE. A novel dual-band transmit/receive (T/R) switch module with an integrated calibration path, hereafter a T/R/Cali-bration switch module, is developed for dual K/Ka-band array systems, especially digital beam-forming antenna array system, using 0.18- m BiCMOS technology. A unique quasi-elliptic dual-bandpass frequency response is achieved in its reception and calibration paths with the use of a composite right/left-handed metamaterial transmission line structure coupled with the Colpitts-style negative-resistance generation circuit. The proposed T/R/Calibration switch module architecture provides a self-calibration for both transmission and reception from the farthest end of an array transceiver excluding antennas, thereby offering an accurate calibration function for the synthetic aperture radar consequently. The newly proposed T/R/Calibration switch topology enhances the opportunity of standalone operation of multi-band array transceivers by the integrated self-calibration capability, while still fulfilling the low-noise and high-power needed for the transceivers for reception and transmission via bidirectional low-noise amplifier/power amplifier, respectively.
