Overview
The Pasternack PE7009-20 is a fixed RF attenuator designed for 75 Ohm impedance systems. It provides a nominal attenuation of 20 dB with BNC connectors, specifically featuring a male-to-female configuration. The unit is rated for up to 1 Watt of power handling and operates effectively within a frequency range extending up to 1 GHz. Constructed with a brass nickel body, this component ensures durability and consistent signal performance in high-frequency applications requiring precise signal reduction.
Feature Summary
- Provides fixed 20 dB signal attenuation for 75 Ohm systems
- Features BNC male to female connector interface
- Rated for 1 Watt power handling up to 1 GHz
Applications
- Signal level adjustment in 75 Ohm RF transmission lines
- Test and measurement setups requiring fixed attenuation
- Cable television (CATV) system signal conditioning
Procurement Notes
Verify the specific model suffix matches the required attenuation value and connector orientation. Confirm that the 75 Ohm impedance specification aligns with your system requirements, as standard RF components often default to 50 Ohms. Check datasheet for detailed VSWR and return loss parameters to ensure compatibility with sensitive measurement equipment.
Selection Notes
Select this model when a fixed 20 dB reduction is needed in a 75 Ohm environment. Ensure the operating frequency does not exceed 1 GHz to maintain rated power handling. Compare against adjustable attenuators if variable control is required, or consider 50 Ohm variants if system impedance differs. Validate connector gender compatibility before integration.
Part Context
This component belongs to Pasternack's line of fixed microwave attenuators. It serves as a passive interconnect device used to reduce signal amplitude without distortion. Unlike variable attenuators, it offers a stable, non-adjustable attenuation value, making it suitable for permanent installations where signal levels are predetermined and constant.
Replacement Considerations
Direct substitutes must match the 20 dB attenuation, 75 Ohm impedance, and BNC connector type. Verify power rating and frequency range compatibility. Generic 50 Ohm attenuators are not electrically equivalent due to impedance mismatch.
