ASML-5822-BLKG

RF Diode Overview

The ASML-5822-BLKG is a Schottky-assisted low power PIN diode limiter manufactured by Broadcom Limited. Designed for receiver protection, it utilizes a series-connected, center-tapped configuration of two silicon elements to safeguard systems from large input signals while maintaining normal operation under standard conditions. The device features a breakdown voltage of 100 V and operates up to a maximum temperature of 150 °C. It is housed in a lead-free R-PDSO-G3 package with three terminals.

RF Diode Feature Summary

• Schottky-enhanced limiting architecture provides a lower threshold compared to conventional self-biased PIN limiters
• Series-connected, center-tapped dual-element configuration for robust signal handling
• Low capacitance design minimizes signal distortion during normal operation

RF Diode Applications

• Receiver system protection against high-power interference
• Low power limiter applications in RF front-ends
• Signal conditioning where minimal insertion loss is required

RF Diode Procurement Notes

Verify the specific suffix BLKG against official datasheets to confirm packaging and compliance details. Confirm availability status as components may be subject to discontinuation or supply constraints. Ensure compatibility with existing PCB footprints and thermal management requirements before integration.

RF Diode Selection Notes

Select this component when low limiting thresholds are critical for protecting sensitive receiver stages. Compare its 0.375 pF maximum capacitance against other limiters to ensure signal integrity at target frequencies. Verify that the 100 V breakdown rating aligns with the expected peak voltages in the application circuit.

RF Diode Part Context

This part belongs to Broadcom's portfolio of Schottky-assisted PIN diode limiters, which includes variants such as the ASML-5829. These devices are engineered to offer cost-effective alternatives to multi-chip solutions by integrating amplifier and mixer functions or protection circuits into single surface-mount packages.

RF Diode Replacement Considerations

The ASML-5829 is a documented variant within the same product family offering similar Schottky-assisted limiting functionality. Verify pinout compatibility and electrical specifications before substituting.
