DATA SHEET Surface Mount Schottky Quad Mixer Diodes Applications * High-volume commercial systems * Modulators and frequency multipliers * Double balanced mixers Features * Tight parameter distribution * Available as ring quads, crossover quads, bridge quads, and octoquads * 100% DC tested * Packages rated MSL1, 260 C per JEDEC J-STD-020) Description Skyworks offers a series of low-cost quad mixer diodes in an SOT-143 package. This series includes low, medium, and high barrier junctions as ring quads, crossover quads, and bridge quads. Octoquad rings are also offered for high dynamic range applications. These devices are constructed using Skyworks monolithic chip technology, ensuring uniformity of electrical characteristics for each junction. The low capacitance of Skyworks ring and crossover quads is optimal for double balanced mixer applications that cover wireless frequencies into the C-band. The bridge quads are designated for modulators and frequency multiplier applications. These diodes are 100 percent DC tested and deliver tight parameter distribution, which minimizes performance variability. They compliment the Skyworks product line of Schottky singles and pairs available in SC-70, SC-79, SOD-323, SOT-23, and SOT143 packages. Table 1 describes the various packages and markings of the Schottky quad mixer diodes.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
