DATA SHEET

DDC, CDC, SMS Series: Zero Bias Silicon Schottky Barrier

Detector Diodes

Applications

x Microwave Integrated Circuits

x Detectors

Features

x High sensitivity

x Low video impedance

x Packages rated MSL1, 260 qC per JEDEC J-STD-020)

Skyworks offers lead (Pb)-free, RoHS (Restriction of

Hazardous Substances) compliant packaging.

TSS is a parameter that best describes the use of a diode as a video

detector. It is defined as the amount of signal power, below a one

milliwatt reference level, required to produce an output pulse with

an amplitude sufficient to raise noise fluctuations by an amount

Description

Skyworks packaged, beam-lead and zero-bias Schottky barrier

detector diodes are designed for applications through the K band.

The choice of barrier metal and process techniques results in a

group of diodes with a wide selection of video impedance ranges.

equal to the average noise level. TSS is approximately 4 dB above

the minimum detectable signal.

Voltage output is another useful parameter since it can be used in

the design of threshold detectors and power monitor circuits. Since

voltage output is a function of the diode’s video impedance, a

different minimum value is specified for each video impedance

range.

Packaged diodes are suitable for use in waveguide, coaxial, and

stripline applications. Beam-lead and chip diodes can also be

mounted in a variety of packages.

The DDC, CDC, and SMS series of Schottky diodes are especially

well suited for use in Microwave Integrated Circuit (MIC)

applications where the chip and wire approach is more desirable.

Mounted beam-lead diodes can be easily used in MIC, stripline, or

other such circuitry.

The absolute maximum ratings for the DDC, CDC, and SMS series

of Schottky diodes is provided in Table 1. Electrical and physical

specifications are provided in Table 2. Package types for the

epoxy and hermetic diodes are listed in Table 3.

Typical performance characteristics are shown in Figures 1

through 8. Typical video detector circuits are shown in Figure 9.

The multi-octave, high-sensitivity circuit would be used in Electronic

Countermeasures (ECM) and similar applications. An RF matching

structure that presents maximum power at the diode junction must

be incorporated to ensure maximum sensitivity.

Applications

The DDC, CDC, and SMS series of zero-bias Schottky diodes are

designed for detector applications through 26 GHz and are useful

up to 40 GHz. They require no bias and operate efficiently even at

tangential signal power levels. Since they require no bias, noise is at

a minimum. A low video impedance means a short R-C time

constant and, therefore, wide video bandwidth and excellent pulse

fidelity.

The broadband low-sensitivity circuit would be used where a low

input VSWR is required. In this circuit, low VSWR is accomplished by

the use of the 50 Ω terminating resistor. Sensitivity, however, is

degraded by typically 10 dB from the multi-octave, high-sensitivity

circuit. The most common use for this circuit is in a broadband, flat

detector used primarily in the laboratory.

As power monitors, these diodes may also be used to directly drive

metering circuits even at low power input levels. These diodes are

categorized by Tangential Signal Sensitivity (TSS), voltage output,

and video impedance for detector applications.
