R413830121

Attenuators Overview

The R413830121 is a fixed in-line RF attenuator manufactured by Radiall USA, Inc. It features SMA connectors and provides a nominal attenuation of 30 dB across a frequency range of 0 Hz to 26.5 GHz. The component is rated for a maximum power handling capacity of 2 W and operates within a standard 50 Ohm impedance system. Designed for robust performance, it supports an operating temperature range from -55°C to +125°C. The unit is supplied in bulk packaging and weighs approximately 18.373 grams.

Attenuators Feature Summary

• Provides precise 30 dB signal attenuation for high-frequency applications
• Operates effectively up to 26.5 GHz with SMA interface connectivity
• Handles continuous power loads of up to 2 Watts
• Engineered for wide thermal stability between -55°C and +125°C

Attenuators Applications

• RF test and measurement equipment requiring precise signal reduction
• High-frequency communication systems operating above 18 GHz
• Military and aerospace electronic subsystems demanding wide temperature tolerance
• Instrumentation circuits needing stable 50 Ohm impedance matching

Attenuators Procurement Notes

Verify the specific connector gender and mating compatibility before integration, as SMA interfaces require precise alignment. Confirm that the 2W power rating aligns with peak signal levels in your circuit to prevent damage. Ensure the 26.5 GHz upper frequency limit meets your application's spectral requirements. Check RoHS and REACH compliance documentation for regulatory adherence in your region.

Attenuators Selection Notes

Select this model when a fixed 30 dB attenuation is required at frequencies extending beyond 18 GHz. Consider the physical dimensions and weight if space constraints are critical. Compare against lower-frequency variants like the R413820000 if operation below 18 GHz suffices, as they may offer different cost structures. Ensure the SMA connector type matches existing cable assemblies or panel interfaces.

Attenuators Part Context

This component belongs to Radiall's line of connectorized attenuators designed for interconnect applications. It serves as a passive device to reduce signal amplitude without introducing significant distortion. The series is characterized by high repeatability and low VSWR, making it suitable for precision RF environments where signal integrity is paramount across broad bandwidths.

Attenuators Replacement Considerations

Direct substitutes include other 30 dB SMA attenuators from Radiall such as the R413830000 series, provided frequency and power ratings match. Cross-manufacturer replacements must verify identical 50 Ohm impedance, 2W power handling, and SMA connector standards to ensure mechanical and electrical compatibility without circuit modification.
