A High Efficiency Frequency Doubler for 100 GHz

An Assessment of Available Models for the Design of Schottky-Based Multipliers Up to THz Frequencies

“…and ( ) have been assumed to relate and for the multipliers in this section. These values are in accordance with published data [7], [10], [55].…”

“…However, in real circuits, coupling the input power to the diodes and the output power to the circuit presents limitations [7], [10], [54]. Thus, to account for these losses in our simulations, the efficiencies predicted for the diodes must be modified by the coupling efficiencies of the input and output circuits to obtain the flange-to-flange efficiency of the circuit [55], [56] as (1) where is the input power delivered to the circuit, is the output power delivered to the external load, is the input power delivered to the diodes, is the output power delivered by the diodes to the output, represents the coupling factor of the input power, and is the coupling factor of the output power. and ( ) have been assumed to relate and for the multipliers in this section.…”
