Enabling Passive Components for High-Power Wideband Millimeter Wave Repeater Applications

A suit of enabling passive components covering entire V-and W-bands, i.e. 45-110 GHz, is built for the support of future RF repeater research and development efforts. Concerns such as loss, power handling, dispersion, and singlemode bandwidth are considered to design a custom double-ridge waveguide and components including antennas, bends, twists, dividers, hybrids, couplers, filters, and decoupling surfaces, just to name a few. Results show that the developed technology can pave the way for efficient, low-cost integrated wideband or multiband millimeter wave systems.
