An effective analysis method is proposed for broadband GaAs Schottky diode-based frequency multipliers. Frequency multipliers output power nulls in the working frequency band have been estimated and removed from the perspective of multiplier transmission notches. Transmission characteristics of the input signal from radio frequency RF input port to Schottky lumpports and the desired harmonic from Schottky lumpports to RF output port are analyzed. Key circuit parts and their dimensions that result in transmission notches are intuitively calculated and analyzed based on 3-D electromagnetic simulation. To verify the above-mentioned technique, three multiplier prototypes based on single, dual, and reverse Schottky junction diodes are fabricated and measured. The measured output power nulls coincides with simulated transmission notches. The proposed method can be utilized to intuitively and quickly remove output power nulls in broadband frequency multipliers working frequency band.
