MADL-011021-14210G

RF Diode Overview

The MADL-011021-14210G is a silicon PIN limiter diode from the MADL series, featuring gold-doped die technology. It operates within the 10 MHz to 18 GHz frequency range and utilizes an ODS-1421 rectangular contact chip outline measuring 0.381 mm by 0.178 mm. Key electrical specifications include a breakdown voltage of 20 V to 35 V, a junction capacitance of 0.23 pF at 0 V reverse bias, and a series resistance of 2.0 Ohms at 500 MHz. The device exhibits a carrier lifetime of 10 ns and a thermal resistance of 35 °C/W. High signal performance metrics indicate a recovery time of 8 ns, with 1 dB limiting power at 41 dBm and flat leakage power at 10 dBm.

RF Diode Feature Summary

• Gold-doped silicon construction for optimized fast signal response and recovery times
• Rectangular contact design on the ODS-1421 substrate for specific mounting configurations
• Silicon nitride passivation ensuring proven reliability in high-signal applications

RF Diode Applications

• Passive limiter control circuits for receiver protection
• Protection of sensitive low noise amplifiers (LNA)

RF Diode Procurement Notes

Verify the specific package configuration against the datasheet's available case styles table before ordering. Confirm that the ODS-1421 rectangular contact outline matches the intended assembly requirements. Ensure handling procedures account for the discrete die nature of the component to prevent contamination or mechanical damage during installation.

RF Diode Selection Notes

Select this part when fast recovery time is prioritized over low flat leakage, as indicated by the gold-doped specification. Compare the 10 ns carrier lifetime against non-gold doped alternatives if lower leakage is required. Verify that the 2.0 Ohm series resistance meets the insertion loss constraints of the specific circuit topology.
