PE7221-40

Overview

The Pasternack PE7221-40 is a fixed RF attenuator designed for microwave applications. It features SMA female to SMA male connectors and provides a nominal attenuation of 40 dB. The device operates within a frequency range of 0 Hz to 6 GHz. It has a power rating of 100 Watts at the stated attenuation value. The impedance is 50 Ohms. The unit utilizes a directional black finish.

Feature Summary

• Provides fixed 40 dB signal attenuation
• Supports frequencies up to 6 GHz
• Rated for 100 Watts power handling
• Features SMA female to SMA male interface

Applications

• Microwave test and measurement setups
• RF signal level reduction in communication systems
• Laboratory equipment calibration

Procurement Notes

Verify the connector gender configuration matches the system requirements, as this model specifies SMA Female to SMA Male orientation. Confirm that the 100 Watt power rating aligns with the operational power levels of the intended application. Ensure the 6 GHz maximum frequency covers the required bandwidth. Check for any specific mounting or thermal management needs associated with high-power dissipation in the installation environment.

Selection Notes

Select this component when a high-power fixed attenuation solution is required for frequencies extending to 6 GHz. The 100 Watt rating distinguishes it from lower-power variants suitable for general-purpose use. Consider the SMA interface compatibility with existing cabling infrastructure. Evaluate the physical size and weight constraints against the available space in the assembly. Compare performance metrics with other Pasternack models if higher frequencies or different connector types are needed.
