PE8028

Overview

The Pasternack PE8028 is a PIN diode-based Schottky limiter designed for RF applications within the 500 MHz to 1 GHz frequency range. It features an SMA connector interface and supports a peak power handling capacity of 100W. The device maintains a flat leakage level of 14 dBm (0.02 W) at an input power of 30 dBm, with a maximum insertion loss of 0.5 dB. Operating temperatures span from -55°C to +90°C.

Feature Summary

• Utilizes PIN diode technology for signal limiting
• Provides consistent flat leakage performance
• Supports high peak power handling

Applications

• RF system protection against over-power events
• Transmitter output stage safeguarding
• Receiver front-end interference mitigation

Procurement Notes

Verify that the SMA connector gender and cable attachment method match your specific system requirements. Confirm that the operational temperature range of -55°C to +90°C aligns with your environmental conditions. Ensure the 100W peak power rating exceeds your system's maximum expected signal levels to prevent component failure.

Selection Notes

Select this component when a wideband limiting solution is required between 500 MHz and 1 GHz. Consider the 0.5 dB insertion loss impact on overall system gain. Evaluate the 14 dBm leakage floor against receiver sensitivity requirements. Verify compatibility with existing SMA infrastructure in the signal chain.

Part Context

This limiter belongs to Pasternack's general-purpose RF IC limiter series. It serves as a protective element within radio frequency circuits, distinct from passive cable assemblies or active amplifiers. The device integrates semiconductor limiting mechanisms into a standard coaxial connector form factor for easy integration.
