Product: 25W Bi-Directional Fixed Attenuator, 3 dB ±0.5 dB, SMA Male to Female, 50Ω Key benefits - Controls signal level precisely: reduces power by 3 dB (±0.5 dB) to protect sensitive receivers and prevent overload. - Minimizes reflections and mismatch: low VSWR (≤1.20) preserves signal integrity across the specified band. - Wide frequency coverage and rugged operating range: supports DC to 3 GHz and operates from −55°C to +125°C for lab and field use. - Simple inline solution with SMA Male to Female connector for direct insertion into 50Ω RF signal chains. Specifications - Quantity: 1 unit per lot - Type: Bi-directional fixed attenuator (works the same in either direction) - Attenuation: 3 dB ±0.5 dB - Maximum input power: 25 W - Frequency range: DC to 3 GHz - VSWR: ≤1.20 - Connector: SMA Male to SMA Female - Impedance: 50 Ω - Temperature range: −55°C to +125°C Why customers need it - Protects downstream equipment from excessive signal power while maintaining impedance matching. - Provides a predictable, repeatable attenuation for testing, calibration, or system-level level-setting. - Compact SMA interface integrates easily with standard 50Ω test and RF equipment without adapters. Compatibility and performance notes - Designed for 50Ω systems with SMA connectors. Ideal for use with SMA-equipped spectrum analyzers, network analyzers, signal generators, receivers, transceivers, and amplifiers operating at or below 3 GHz. - The bi-directional design allows installation in either orientation without changing performance. - Attenuation tolerance (±0.5 dB) and VSWR ≤1.20 ensure accurate level control with minimal added reflection. Practical use scenarios 1) Test bench protection: Place the attenuator between a signal generator and a sensitive receiver or analyzer to reduce input level by 3 dB and avoid overload during bench measurements. 2) System integration and level matching: Insert between transmitter and amplifier or between amplifier stages to achieve required input levels and maintain 50Ω matching. 3) Field installations and troubleshooting: Use inline when connecting antennas, repeaters, or transceivers to adjust signal levels, prevent interference, or simulate cable loss during installation and diagnostics. What to expect in operation - Reliable, repeatable attenuation across DC–3 GHz with low insertion loss variability. - Stable performance across the specified temperature range for both indoor and harsh-environment deployments. - Easy installation into standard SMA 50Ω signal paths. Ordering information - Each lot contains one (1) 25W bi-directional fixed attenuator with the specifications listed above.
