Subharmonically Pumped Mixers

Subharmonically pumped mixers are GaAs beam lead Schottky diode- or MMIC device-based mixers. The subharmonically pumped mixers employ a broadband circuitry and balanced structure to offer low conversion loss and harmonics and are widely used in many communication systems where a superior harmonic and spurious performance is critical. In addition, these mixers have an extremely low LO signal leakage at the RF port. Furthermore, an LO frequency at half the RF frequency reduces the system cost tremendously. The below standard offering covers the frequency range of 18 to 110 GHz with a typical RF bandwidth that is up to the full waveguide band. Although the non-biased version is the baseline design, externally-biased options are available. Additionally, the standard models focus on full bandwidth operations for most applications, but custom models can be offered to meet specific application needs.
