DATA SHEET

CDC7630/7631 and DDC2353/2354 Series: Zero Bias Silicon

Schottky Barrier Detector Diodes

Applications

• Microwave integrated circuits

• Detectors

Features

• High sensitivity

• Low video impedance

• Packages rated MSL1, 260 °C per JEDEC J-STD-020)

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

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

the minimum detectable signal.

Description

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

detector diodes are designed for applications through the K band.

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

The choice of barrier metal and process techniques results in a

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

such circuitry.

epoxy and hermetic diodes are listed in Table 3. SPICE model

parameters for the CDC7630/7631 series are defined in Table 4.

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 CDC and DDC 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

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.

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.

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.

Package dimensions are provided in Figures 10 through 15.
