Abstract :
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
