CDC7630-000

RF Diode Overview

The CDC7630-000 is a bare die, beam-lead zero-bias silicon Schottky barrier detector diode manufactured by Skyworks Solutions Inc. Designed for applications through the K band, it operates efficiently at tangential signal power levels without requiring external bias. The device features a video impedance range of 2000 to 6500 ohms and a maximum Tangential Signal Sensitivity (TSS) of -52 dBm. It has an absolute maximum reverse voltage rating of 2 V and can withstand an RF input power of up to 75 mW at 25 °C. The component utilizes the 571-006 outline drawing package.

RF Diode Feature Summary

• Zero-bias operation ensures minimum noise performance by eliminating the need for external biasing.
• Low video impedance provides a short R-C time constant, resulting in wide video bandwidth and excellent pulse fidelity.
• Beam-lead construction facilitates direct integration into Microwave Integrated Circuits (MIC), stripline, or chip-and-wire circuitry.

RF Diode Applications

• Microwave integrated circuits
• Video detectors operating through 26 GHz and useful up to 40 GHz
• Power monitors driving metering circuits at low power input levels

RF Diode Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Skyworks documentation before procurement. Confirm that the bare die beam-lead configuration matches the intended assembly process. Ensure electrostatic discharge precautions are implemented during handling, as the device is sensitive to static charges. Check for any recent product discontinuation notices or lifecycle status updates directly from the manufacturer.

RF Diode Selection Notes

Select this component when designing high-sensitivity multi-octave detector circuits where maximizing sensitivity is critical. The 2000 to 6500 ohm video impedance range suits applications requiring specific load matching for optimal voltage output. Consider the -52 dBm TSS specification for detecting signals near noise floors. Evaluate the 571-006 beam-lead package dimensions to ensure compatibility with the target substrate and bonding methods.

RF Diode Part Context

The CDC7630-000 belongs to the CDC and DDC series of zero-bias Schottky diodes designed for microwave detector applications. This series offers a selection of video impedances categorized by Tangential Signal Sensitivity and voltage output. The CDC7630 variant specifically targets lower video impedance ranges compared to the CDC7631, making it suitable for broadband flat detectors and laboratory measurement equipment requiring low input VSWR.

RF Diode Replacement Considerations

The datasheet lists the DDC2353-000 as a similar device within the same series, sharing identical electrical specifications including an 8 mV detected output voltage and a 2000 to 6500 ohm video impedance range. However, the DDC2353 uses the 491-006 package outline, which differs physically from the 571-006 beam-lead package of the CDC7630. Verify mechanical compatibility if substituting.
