Local oscillator balun using inverting circuit |
摘要 |
The present invention relates to a local oscillator balun using an inverting circuit. The local oscillator balun using an inverting circuit comprises a complementary output converting circuit for amplifying a weak signal as a single signal from a local oscillator to produce two signals; a differential amplification circuit for producing two signals having a given amplitude from the two signals of said complementary output converting circuit; and an inverting circuit for inverting the two signals of the differential amplification circuit. Thus, a complementary signal having the maximum amplification and small phase difference can be produced. Therefore, the present invention can implement the maximum gain and small local oscillating leakage of the frequency mixer in a Gilbert type high frequency double balance frequency mixer.
