  • Abstract
    This paper presents the design and measurement results of a high dynamic range quadrature modulator integrated in Atmel´s 50 GHz f1 SiGe foundry technology. An integrated differential cascode output amplifier boosts the output compression point to >14.3 dBm (3.5 Vpp diff. input referred) without sacrificing dynamic range. A three-stage polyphase filter provides high image rejection from 700 MHz to 2700 MHz.
