ABSTRACT:
Microwave circuitry is disclosed for a distortion generating circuit. Input and output baluns are disposed on the tap surface of a substrate while secondary and primary conductors are respectively juxtaposed under these baluns. Four diodes connected in a star configuration are coupled between the primary and secondary conductors. The carrier signal may be fed into the input balun which is coupled to the secondary conductors and across the diode star configuration, generating intermodulation signals while suppressing the carrier signals. The intermodulation signal is coupled from the primary conductors to the output balun where it may be fed to a microwave amplifier to cancel intermodulation by-products thereof. A DC signal may be impressed across the diode star configuration to adjust the amplitude of the intermodulation signal generated by the diodes.
