MADL-011012-001

RF Diode Overview

The MADL-011012-001 is a lead-free surface mount high power limiter operating from 0.3 to 1.0 GHz. It integrates the equivalent of 20 PIN, Schottky, limiter diodes, capacitors, inductors, and resistors within a compact ceramic package measuring 10.1 x 6.2 x 3.2 mm³. The device provides superior low and high signal performance without requiring DC bias. Key electrical specifications include a maximum insertion loss of 0.55 dB at 1000 MHz and a return loss of 25 dB at 500 MHz. It handles up to 54 dBm CW incident power at +85°C and features a hermetic seal with a fine leak rate less than 5x10⁻⁸ atm·cc/s.

RF Diode Procurement Notes

Verify the specific ordering suffix against current MACOM documentation before procurement. Confirm that the required quantity matches the bulk packaging configuration listed in the official datasheet. Ensure that handling procedures account for electrostatic discharge sensitivity, as these are HBM Class 1B devices. Cross-reference the RoHS compliance status with the latest regulatory directives applicable to your region.

RF Diode Selection Notes

Select this component when designing circuits requiring robust protection against high incident power levels within the 0.3 to 1.0 GHz spectrum. Evaluate the thermal management requirements carefully, as the exposed paddle must be connected to RF, DC, and thermal ground. Consider the 50 Ohm system impedance and ensure that the application does not demand operation beyond the specified junction temperature limits.
