Advanced millimeter-wave radar modules for helicopter landing aid
Miniaturized millimeter-wave radar modules working at 94 GHz enable advanced helicopter landing aids.These modules make use of the 100 nm metamorphic HEMT technology developed at Fraunhofer IAF. The frequency modulated continuous wave (FMCW) radar integrates a broadband VCO, an MPA/HPA, a Lange-Coupler, an LNA, a Wilkinson power splitter, and an IQ-Mixer on a single monolithic microwave integrated circuit (MMIC)
