Texscan RA-73 Adjustable Step RF Attenuator SMA Female Connectors 0-10 dB
The Texscan RA-73 is a handheld inline RF attenuator with SMA female connectors. It provides adjustable attenuation in 11 discrete steps from 0 to 10 dB via rotary dial selection.
Specifications & What's Included
- Model: RA-73
- Attenuation Range: 0–10 dB (11 steps)
- Connectors: SMA Female (2)
- Adjustment: Rotary dial (step attenuator)
- Measured Center Pin Impedance: 4.8–13.0 Ohm (approximate, across all dial positions)
- Reference Impedance: 155.8 Ohm (approximate)
- Form Factor: Handheld / Inline
Applications
Step attenuators are used in RF and microwave test setups, transmitter/receiver signal level adjustment, and equipment protection during measurement and troubleshooting. The RA-73 is found in telecom, broadcast, and industrial RF applications where controlled signal reduction is required without continuous tuning.
Condition: Used
This Texscan RA-73 adjustable step RF attenuator has been inspected and is in working condition. We measured the resistance (ohms) across the center pins at each dial position using a multimeter. Approximate readings from dial 0 through 10 and the Zo position are: 4.8, 5.4, 6.3, 7.1, 8.1, 8.9, 9.8, 10.7, 11.4, 12.4, 13.0, and 155.8 ohms. The aluminum body shows light surface wear consistent with age and prior lab use. The dual SMA female connectors show some tarnishing on the coupling hardware, visible in our photos. The rotary dial and dB scale markings are clean and legible. Please view our photo set and contact us if you have any questions.
