Frequency Multipliers
A series of broadband frequency multipliers is available with output frequencies between 18 and 110 GHz. The use of GaAs diodes on a suspended substrate circuit allows an extremely compact device. Circuit symmetry is used to enhance either even or odd harmonics while suppressing unwanted odd or even harmonics. These devices can be used as higher order even or odd harmonic multipliers with reduced efficiency. All of these multipliers have maximum input power +23 dBm for temperature less than +50°C.
