Custom MMIC Introduces GaAs Sub-Harmonic Mixers for High-Frequency Applications

Custom MMIC has added a new product category, including three new GaAs Sub-harmonic mixers to its growing list of high-performance MMICs. 

The CMD303, CMD310/C3 MMICs cover frequency ranges of 13-21 GHz and 20-32 GHz respectively, with excellent conversion loss and isolation. Sub-harmonic mixers are driven by a local oscillator (LO) signal that is an integer fraction, or sub-harmonic, of the desired LO frequency. This eases the design, layout, and cost of the LO source for microwave frequency designs. These new mixers operate with a x2 LO, meaning the user needs to provide the mixer with an LO at half the desired mixing frequency.
