2690-1014

Overview

The MACOM 2690-1014 is a passive solid-state RF limiter designed for receiver protection across the 2 GHz to 18 GHz frequency range. It features an insertion loss of 2.2 dB and handles a maximum input power of 33 dBm (2 W). The device maintains a flat leakage power of 0.06 W (18 dBm) to safeguard sensitive downstream components. Operating within a temperature range of -55°C to +85°C, it provides reliable signal limiting in high-power environments.

Feature Summary

• Passive solid-state construction for robust receiver protection
• Broadband octave and multi-octave performance coverage
• Low insertion loss characteristics for minimal signal degradation

Applications

• RF receiver front-end protection
• Test and measurement equipment signal conditioning
• Communication systems requiring high-power tolerance

Procurement Notes

Verify that the specific application requires a passive limiter rather than an active amplifier or switch. Confirm that the operating frequency range of 2 GHz to 18 GHz aligns with the system requirements. Ensure the thermal management solution supports the specified operating temperature range of -55°C to +85°C. Check that the SMA termination style matches the existing board layout and connector specifications.

Selection Notes

Select this component when broadband protection from 2 GHz to 18 GHz is required without active biasing. Consider the 2.2 dB insertion loss impact on overall system noise figure. Evaluate if the 33 dBm input power handling meets peak signal expectations. Verify compatibility with SMA connectors and surface-mount QFN packaging constraints.

Part Context

This part belongs to MACOM's standard 2690 series of completely passive solid-state receiver protectors. The series utilizes unique designs to achieve octave and multi-octave performance. These limiters are engineered to provide consistent protection across wide bandwidths while maintaining low insertion loss.

Replacement Considerations

Consult official MACOM documentation for direct cross-reference substitutes. Verify pinout compatibility and electrical parameter equivalence before substitution.
