Quadrature Subharmonic Coupled Oscillators for a 60GHz SiGe Scalable Phased Array

This paper describes an integrated coupled oscillator array in SiGe for millimeter wave applications. The design focuses on scalable radio architectures where multiple dies are tiled to form larger arrays. A 2 times 2 oscillator array for a 60GHz transmitter is designed with integrated power amplifiers and antennas. The 2 times 2 array demonstrates a 200MHz locking range and 1 times 4 array formed by two adjacent chips has a 60MHz locking range. The phase noise of the array is below -110dBc/Hz at a 1MHz offset
