Abstract
This paper describes the design and the measured results of fully integrated QPSK linear vector modulator realized on GaAs MMIC technology in Ku band. In 10.7 GHz - 12.75 GHz band (Telecom band in space applications), the measurements of modulator demonstrate side band and carrier rejection better than 40 dBc with power dissipation of 850 mW. Up to now, only one MMIC QPSK linear vector modulator has been published in Ku band. This QPSK modulator was constituted by several MMICs implanted in the same test fixture and its power dissipation was high. [1]
