Injection Locked 100 GHz LO Network, For A 32 Channel 220 GHz Imaging Array

Authors:
Israel Galin, David S. Zacharias
Abstract:
Multi-channel array receivers, for millimeter-wave (MMW) imagers, require local-oscillator distribution network with challenging electrical and packaging performance. This paper presents a local-oscillator (LO) distribution network driving 32 subharmonic (X2) mixers, of a 220 GHz imaging array. The LO distribution network features 32 outputs - each injection-locked and phase controlled relative to a master oscillator - yielding more than 20 mW power at each output. The waveguide network configuration facilitates LO distribution to a compactly packaged, 12" linear array of mixers. The paper provides a complete description and data for this MMW LO distribution network.
