For this one year research project, for the first time, we have successfully combined the pre-distorter, and the variable-gain amplifier into one circuit, which increases the integration level of linearization techniques in transmitter designs, that also published in IEEE IMS. On the other hand, we have successfully developed millimeter-wave IQ modulators with linearization techniques, which have been published in APMC and IEEE transaction of MTT. |
