MADL-011014-001000

RF Diode Overview

The MADL-011014 is a lead-free surface mount high power limiter operating from 1 to 2 GHz. It integrates equivalent PIN, Schottky, and passive components in a compact ceramic package requiring no DC bias. The device provides superior low and high signal performance for receiver protection applications. Key electrical specifications at +25°C include an insertion loss of 0.35 dB (typical) at 1.2–1.4 GHz and a return loss of 19 dB (typical). It handles +55 dBm peak incident power and +53 dBm CW incident power at +85°C. Flat leakage power is +19 dBm, with a recovery time of 3.5 µs.

RF Diode Procurement Notes

Verify the specific ordering suffix when purchasing. The -001000 suffix denotes the standard hermetic seal package. Confirm current availability and lead times directly with authorized distributors or the manufacturer, as supply conditions may vary. Ensure compliance with RoHS directives and handle according to ESD precautions specified in the datasheet.

RF Diode Selection Notes

Select this component for applications requiring high power limiting between 1 and 2 GHz without DC bias. Evaluate thermal management requirements, as junction temperature affects power handling ratings. Ensure source and load VSWR remain within 1.2:1 limits to maintain specified performance. Compare leakage power and recovery time against system sensitivity requirements.
