A Study on Design of Reflect for Type Frequency Doubler in K-Band

Abstract

In this paper, a reflector type frequency doubler for local oscillator at 24㎓ is designed and fabricated with ne71300-N MESFET. Optimum source and load impedances are decided through a multiharmonic load pull simulation technique. A conversion gain can be improved using the reflector and fundamental and third harmonics are well suppressed with open stub of λ/4 length Measured results show output power at 0㏈m of input power is -3.776㏈m, conversion gain 0.736㏈, harmonic suppression 41.064㏈c, respectively.

Key Words: frequency doubler;multiharmonic load pull;reflector;conversion gain
