A 2 x 2 Beam Divider for an array local oscillator at 1.37 THz

A 2 x 2 local oscillator beam divider for pumping a hot electron bolometer mixer array is designed at 1370 GHz. Traditional rectangular waveguide based H-plane and E-plane junctions are used to construct the feeding network. Two 400-μm thick silicon wafers are used to build the feeding network, and...

Description
Summary:A 2 x 2 local oscillator beam divider for pumping a hot electron bolometer mixer array is designed at 1370 GHz. Traditional rectangular waveguide based H-plane and E-plane junctions are used to construct the feeding network. Two 400-μm thick silicon wafers are used to build the feeding network, and an aluminum plate is used to build the circular horn array. Multilayer micromachining and multilayer stack assembling are the two key technologies employed in building this beam divider.
