Abstract: In some embodiments, a system may include a passive uniplanar single-balanced millimeter-wave mixer. In some embodiments, a three-port diode-tee IC forming a mixer core is coupled between an end of a slotline balun and a second coplanar balun. The operational bandwidth of a mixer structure is enhanced by optimizing the distance between the mixer diode-tee core and the back-short circuits. The frequency separation of LO and IF signals may be accomplished by means of stand-alone three-port filter-diplexer device. The system may allow wider than a frequency octave operational bandwidth for a frequency converter device all the way into millimeter wave frequencies at the same time as supporting the operational bandwidth for baseband IF signal over more than six frequency octaves. In some embodiments, the system may accomplish a 500 MHz to 34.5 GHz continuous IF bandwidth with RF signal sweeping from 33 GHz to 67 GHz and local oscillator at 67.5 GHz fixed frequency.

Abstract: A miniaturized dual-balanced mixer circuit based on a trifilar layout architecture is proposed, which is designed for use to provide a frequency mixing function for millimeter wave (MMW) signals, and which features a downsized circuit layout architecture that allows IC implementation to be more miniaturized than the conventional star-type dual-balanced mixer (DBM). The proposed miniaturized dual-balanced mixer circuit is distinguished from the conventional star-type DBM particularly in the use of a trifilar layout architecture for the layout of two balun circuit units. This feature allows the required layout area to be only about 20% of that of the conventional star-type DBM.

Abstract: The present invention utilizes an even harmonic mixer for canceling a local oscillator (LO) leakage signal. The apparatus for canceling the LO leakage signal includes an in-phase divider, an intermediate frequency (IF) phase divider, an even harmonic mixers, an RF signal phase combiner and a band pass filter (BPF). The in-phase divider divides an LO signal into two in-phase LO signals, wherein the LO signal is inputted from an exterior LO. The IF phase divider divides an IF signal into two out-of-phase IF signals of which a phase difference is 90null, wherein the IF signal is inputted from an exterior means. The even harmonic mixer outputs two out-of phase RF signals of which the phase difference is 90null, after even-harmonic mixing of two in-phase LO signals divided by the in-phase divider and two out-of-phase IF signals divided by the IF phase divider. The RF signal phase combiner plays a role in canceling an image signal in the RF signal by combining two out-of-phase RF signals outputted from the even harmonic mixer. The BPF is used for canceling a residual component of the leakage signal in the RF signal outputted from the RF signal phase combiner.
