Abstract :
A five-element frequency tripler at 450 GHz in a spatial power dividing/combining circuitry has been investigated. The individual triplers are realized with 4 AlGaAs/GaAs-heterostructure barriers bonded onto a membrane-supported coplanar circuit. Dual-offset reflectors together with dielectric phase gratings are applied to achieve efficient power transfer to/from the active devices. The single-element triplers have a maximum output power of 1.05 mW at 451.8 GHz (efficiency: 1.3%). The unsaturated 5-element frequency tripler generates a maximum output power of 2.01 mW at 451.5 GHz.
