Product Description
SMA Coaxial Attenuator - 3dB
The SMA-ATT-3 dB SMA male-to-female coaxial attenuator is a compact passive RF component designed to reduce signal power to a controlled level while maintaining signal integrity. With 50-ohm SMA connections, it installs directly in-line between compatible RF equipment, coaxial cables, antennas, adapters, and test instruments.
It can be used for RF signal-level control, laboratory testing, wireless communications, antenna systems, radio equipment, spectrum analyzers, receivers, transmitters, and RF test setups. It is particularly useful when a signal needs to be reduced before reaching sensitive equipment or when a specific RF power level is required for testing and measurement.
