25 W SMA attenuator (DC to 3 GHz / 4 GHz) Key benefits Protects sensitive receivers and test equipment by reliably reducing signal power up to 25 W, preventing overload and damage. Provides precise signal-level control with a broad selection of fixed attenuation values to match measurement and system requirements. Simple compatibility with standard 50 Ohm RF systems and SMA connections for straightforward integration into bench setups and field equipment. What it does and why it matters Attenuates RF signals while preserving impedance matching and signal integrity in 50 Ohm systems, helping maintain measurement accuracy and stable system performance. Reduces the need for careful transmitter power adjustments or risk of damaging downstream components when connecting high-power sources to lower-power devices. Key specifications Power handling: 25 W Connector type: SMA (female RF coaxial connector) Impedance: 50 Ohm Frequency range: DC to 3 GHz / 4 GHz Available fixed attenuation values: 1, 2, 3, 5, 6, 10, 15, 20, 30, and 40 dB Notable performance: 30 dB model provides 30 dB attenuation at 4 GHz Compatibility and practical details Designed for use with SMA-equipped equipment and 50 Ohm RF systems commonly found in test benches, signal generators, spectrum analyzers, and communication links. Fixed-value choices let you pick the exact attenuation needed for system leveling or receiver protection without added complexity. Typical use cases Laboratory testing: Insert between a signal source and a measurement receiver to set signal levels precisely and protect instruments during calibration and characterization. Field and production checks: Reduce transmitter power to safe levels for functional testing of receivers and modules without changing transmitter settings. System integration: Match levels between RF modules or attenuate interfering carriers when integrating components in 50 Ohm RF chains. No assumptions about dimensions or materials are made beyond the SMA interface and stated electrical specifications. Choose the attenuation value that fits your application to ensure correct level control and equipment protection.
