Abstract

This paper presents an X/Ku-band fine-tuning frequency synthesizer using a quadrature DDS implemented in a 0.18 mum SiGe BiCMOS technology. The frequency synthesizer comprises a 9-bit quadrature DDS, an 11.7 GHz quadrature VCO and image rejection mixers. The outputs of the quadrature DDS are down-converted to 9.4~11.7 GHz and up-converted to 11.7~14.0 GHz, respectively. The die area of the synthesizer is 3.0times3.0 mm² and the power consumption is 2.6 W under a 3.3 V supply. The chip is measured with a 48-pin leadless free ceramic package and external cooling.
