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 and crossover quads. 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.
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
SOT-143 packages.
Table 1 describes the various packages and markings of the
Schottky quad mixer diodes.

Note 1: Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.

Electrical and Mechanical Specifications
Package and Handling Information
The absolute maximum ratings of the quad mixer Schottky diodes
are provided in Table 2. Electrical specifications are provided in
Table 3.
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
Associated SPICE model parameters are provided in Table 4.
Typical forward voltage characteristics are shown in Table 5.
The quad mixer Schottky diodes are rated to Moisture Sensitivity
Level 1 (MSL1) at 260 C for 5 seconds. They can be used for
lead or lead-free soldering. For additional information, refer to the
Skyworks Application Note, Solder Reflow Information, document
number 200164.
Dimensions for the SOT-143 package are shown in Figure 1, and
tape and reel dimensions are provided in Figure 2.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
