Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances) compliant packaging.
Beam-lead Schottky barrier diodes are categorized by universal
mixer applications in four frequency ranges: S, C, X, Ku, K, and Ka
bands as noted in Table 1. They may also be used as modulators
and high-speed switches.
Beam-lead diodes are suited for balanced mixers, due to their low
parasitics and uniformity.
Description
Skyworks beam-lead silicon Schottky barrier mixer diodes are
designed for applications through 40 GHz. The beam-lead design
reduces the problem of bonding to the very small area
characteristic of low capacitance junctions.
Beam-lead Schottky barrier mixer diodes are made by the
deposition of a suitable barrier metal on an epitaxial silicon
substrate to form the junction. The process and choice of
materials result in low series resistance with a narrow spread of
capacitance values for close impedance control.
A variety of forward voltages are available ranging from low values
for low, or starved, local oscillator drive levels to high values for high
drive, low distortion mixer applications. Beam-lead diodes are
available in a wide range of packages. Capacitance ranges and
series resistances are comparable with the packaged devices that
are available up to, and including, the Ka-band. Unpackaged diodes
are well suited for use in Microwave Integrated Circuits (MICs). The
packaged devices are designed to be inserted as hybrid elements in
strip, transmission line applications.
The absolute maximum ratings of the DME, DMF, and DMJ series
of Schottky mixer diodes are provided in Table 2. Electrical and
physical specifications are provided in Tables 3 through 15.
Typical performance characteristics are shown in Figures 1
through 3. Typical mixer circuits are shown in Figure 4.

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 these devices are designed to be as robust as possible, Electrostatic Discharge (ESD) can damage them. These
devices 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.
