Overview
The Pasternack PE7018-3 is a fixed coaxial attenuator providing 3 dB attenuation. It operates from 0 Hz to 18 GHz with a 50 Ohm impedance. The device features SMA male-to-female connectors and is rated for 25 Watts power handling at the specified attenuation value. Constructed with a black anodized aluminum heatsink body, it ensures thermal stability in high-power RF applications.
Feature Summary
- Fixed 3 dB attenuation value maintained across the operational frequency range
- High power handling capability of 25 Watts at the stated attenuation level
- Integrated black anodized aluminum heatsink body for effective thermal management
- SMA male to SMA female connector interface for standard coaxial integration
Applications
- RF signal level reduction in microwave test and measurement setups
- Impedance matching and isolation between RF components in communication systems
- Power monitoring and control circuits operating up to 18 GHz
- Defense and aerospace electronic subsystems requiring stable attenuation
Procurement Notes
Verify that the required attenuation value is exactly 3 dB and the power rating meets the 25 Watt specification for your application. Confirm the SMA male-to-female connector configuration matches your system cabling. Ensure the operating frequency does not exceed 18 GHz. Check RoHS compliance requirements if applicable to your manufacturing standards. Validate the physical dimensions against your available mounting space.
Selection Notes
Select this component when a precise 3 dB loss is required without variable adjustment. Consider the 25 Watt power rating to ensure safe operation within thermal limits. The SMA interface suits general-purpose RF testing environments. Evaluate the 18 GHz upper frequency limit against your highest signal frequency. The heatsink design supports continuous high-power duty cycles better than unheatsunk variants.
Part Context
This part belongs to the Pasternack RF Attenuators category, specifically as a connectorized fixed attenuator. It is designed for use in coaxial transmission lines where predictable signal reduction is necessary. The product utilizes standard SMA interfaces common in laboratory and industrial RF equipment. It serves as a passive component for managing signal strength in microwave frequencies.
Replacement Considerations
No public confirmed substitute part numbers are documented for this specific model. When replacing, ensure the new component matches the 3 dB attenuation, 50 Ohm impedance, and 25 Watt power rating. Verify that the replacement also supports the 0 Hz to 18 GHz frequency range and uses compatible SMA connectors.
