Find the right RF tool for your specific engineering challenge. Use our wizard or browse common scenarios.
Not sure which tool you need?
With so many attenuator topologies (Pi, T, Bridged-T, L-Pad, Balanced...), it's easy to get confused.
Our Smart Selection Wizard asks you simple questions about your system requirements—like impedance (Z0), variability, and balance—to recommend the mathematically optimal topology.
Common Decision Points
- Do I need to change the attenuation often?
- Are my cables Coax (Unbalanced) or Twisted Pair (Balanced)?
- Are the Input and Output impedances the same?
Common RF Scenarios
Receiver Overload Protection
Protect sensitive ADCs, LNAs, and Spectrum Analyzers from high-power input signals.
50Ω to 75Ω Impedance Matching
Connect 75Ω TV antennas or video cables to 50Ω standard RF test equipment without reflections.
Improving Source VSWR
Use an attenuator to 'mask' a poor return loss and present a clean 50Ω match to your DUT.
Balanced Audio/RF Adjustment
Attenuate XLR or Differential pair signals without breaking Common Mode Rejection (CMRR).
System Integration (Commercial)
When to use connectorized attenuators: Instrument protection, DAS, and High Power testing.
