The FP7 Research for SME project IMAGINE - a low cost, high performance monolithic passive mm-wave imager
front-end is described in this paper. The main innovation areas for the project are: i) the development of a 94 GHz
radiometer chipset and matching circuits suitable for monolithic integration. The chipset consists of a W-band low noise
amplifier, fabricated using the commercially available OMMIC D007IH GaAs mHEMT process, and a zero bias
resonant interband tunneling diode, fabricated using a patented epi-layer structure that is lattice matched to the same
D007IH process; ii) the development of a 94 GHz antenna adapted for low cost manufacturing methods with
performance suitable for real-time imaging; iii) the development of a low cost liquid crystal polymer PCB build-up
technology with performance suitable for the integration and assembly of a 94 GHz radiometer module; iv) the assembly
of technology demonstrator modules. The results achieved in these areas are presented.
