20-120RP-S

Overview

The 20-120RP-S is a fixed RF attenuator manufactured by TTM Technologies, Inc. It provides an attenuation value of 20 dB with a nominal impedance of 120 Ohms and a tolerance of 5%. The component operates within a frequency range from 0 Hz to 4 GHz and supports a power rating of 20 W. Designed for robust performance, it utilizes a half-flange mounting style suitable for chassis installation.

Feature Summary

• Fixed attenuation design providing consistent signal reduction
• Half-flange construction for secure chassis mounting
• High power handling capability for demanding applications

Applications

• RF signal conditioning in communication systems
• Test and measurement equipment setups
• Microwave circuit integration

Procurement Notes

Verify the specific impedance and power requirements against the system design before ordering. Confirm that the half-flange mounting style aligns with the available chassis space and thermal management infrastructure. Ensure the operating frequency range up to 4 GHz meets the application's spectral needs. Check RoHS compliance status if environmental regulations are a strict constraint for the project.

Selection Notes

Select this model when a 120 Ohm impedance environment is required rather than the standard 50 Ohm. The 20 W power rating makes it suitable for high-power transmission lines where significant heat dissipation is necessary. Consider the physical dimensions of the half-flange package to ensure compatibility with existing mechanical structures and cooling solutions in the assembly.

Part Context

This component belongs to the family of planar resistors and RF attenuators produced by TTM Technologies. The manufacturer specializes in RF and microwave components, offering various fixed attenuator options with different impedance values and power ratings to support diverse wireless and industrial electronics designs.

Replacement Considerations

Direct substitutes must match the 120 Ohm impedance and 20 W power rating. Verify that alternative models also support the 0 Hz to 4 GHz frequency range. Ensure the replacement maintains the half-flange mounting style for mechanical compatibility.
