Passive Frequency Multipliers
Passive frequency multipliers are GaAs beam lead Schottky diode- or MMIC device-based multipliers. The multipliers employ a broadband circuitry and balanced structure to offer higher conversion efficiency and continuous frequency coverage for up to full waveguide band operations. The balanced design enhances the desired harmonic output and suppresses unwanted components. The waveguide output filters out the fundamental frequency naturally, which guarantees an excellent input and output signal isolation. Based on the large-signal, nonlinear characteristics of the resistive device, rich harmonics are generated once the RF power is applied. Hence, no external bias is required. The below standard offering covers the frequency range from 26.5 to 110 GHz. While full band models offer moderate output power, higher output powers with narrow bandwidths are available as custom models.
