Abstract

A novel type of coupled line structure has been used on a GaAs monolithic microwave integrated circuit to realise a 90° coupler operating over 2 to 10 GHz. The multilayer nature of the GaAs IC has been used to realise quasiplanar broadside coupled lines. The coupler has been folded to make it small and measures only 1.0×0.8 mm.
