Description
The Isolink silicon Schottky barrier mixer diodes are designed for
applications through 20 GHz.
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. These Schottky barrier
mixer 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.
Schottky barrier diodes are categorized by universal mixer
applications in six 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.

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 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.
