In this paper, RF transceiver for wireless backhaul system was designed and implemented. The requirement of RF transceiver was extracted with system link budget. And, the IF/RF modules composing the transceiver were also designed and fabricated. The implemented RF transceiver was verified with system loop-back test.
Communication transceivers utilizing the inphase/ quadrature (I/Q) up- and down-conversion principle face a common problem of amplitude and phase mismatch. These mismatches result in the generation of an image signal and thus, cause mirror-frequency interference. Moreover, quadrature modulation/demodulation errors also affect the performance of pre-distortion based power amplifier linearization techniques...
