| Zusammenfassung: | An improved active balanced mixer for developing an IF signal by combining an RF signal and a local oscillator signal while providing high conversion gain. The mixer utilizes a series resonant circuit resonant at the IF frequency to reduce degenerative feedback effects at the IF frequency, thereby increasing conversion gain. Circuit is particularly adapted for a receiver in which the received RF signal is relatively close to the receivers IF frequency. |
