MA4L011-186

RF Diode Overview

The MA4L011-186 is a silicon PIN limiter diode from the MA4L series, packaged in the ODS-186 ceramic surface mount style. It features gold-doped die for fast signal recovery and low flat leakage power. Key electrical specifications include a breakdown voltage of 15 to 35 V, junction capacitance of 0.13 pF at -10 V reverse bias, and series resistance of 2.10 ohms at 500 MHz. The device supports high peak incident power up to 7 dBm (50 W) with a maximum recovery time of 30 ns.

RF Diode Feature Summary

• Gold-doped silicon construction provides fast carrier lifetime and rapid signal response times.
• Low insertion loss and noise figure characteristics suitable for sensitive receiver protection.
• High peak and average operating power handling capabilities.
• Small I-region length designed specifically for high-signal applications.

RF Diode Applications

• Passive limiter control circuits
• Protection of low noise amplifiers (LNA)
• Protection of detectors and mixers

RF Diode Procurement Notes

Verify the specific package style suffix against the manufacturer's current case style table before ordering. Confirm that the gold-doped variant meets the required recovery time specifications for the target application. Ensure proper mounting procedures are followed to maintain thermal performance.

RF Diode Selection Notes

Select this component when fast recovery time is prioritized over ultra-low flat leakage. Compare the 15-35 V breakdown voltage against system requirements. Verify compatibility with the ODS-186 ceramic surface mount footprint and associated parasitic values.

RF Diode Part Context

This part belongs to the MA4L, MADL, and MADP series of silicon PIN limiter diodes. These devices utilize small and medium I-region lengths to deliver low insertion loss at zero bias while maintaining robust high-power handling.
