Alan Industries 50SDV79 RF Attenuator

This high precision stepped attenuator from Alan Industries enables controlled RF signal attenuation from 0 up to ~79 dB in 1 dB increments. With 50 Ω impedance and DC-1 GHz bandwidth, this unit is ideal for laboratory test benches, RF systems integration, signal calibration tasks and educational labs requiring adjustable RF level control.

Key features:

• 0-79 dB attenuation range, 1 dB steps

• Tight accuracy: ±0.2 dB for low settings (0-9 dB) within DC-0.5 GHz; ±0.5 dB up to full range, and slightly larger for higher frequencies (up to ±1 dB for 0.5-1 GHz)

• Insertion loss: 0.3 dB max

• SWR: ~1.3:1, 50 Ω matched

• Connectors: SMB (male/female as appropriate)

• Mounting: panel-mountable, compact format — suitable for integration in racks or custom enclosures

• Power rating: Suitable for typical lab signal levels (1 W average)

Applications include:

• RF test & measurement: attenuating signals to protect receivers or simulate level changes

• Calibration benches: stepping attenuation reliably for repeatable results

• RF subsystem development: controlling input or output signal levels in prototypes or production setups

• Educational labs: providing hands-on adjustable attenuation for teaching RF concepts
