PE7337-40

Overview

The Pasternack PE7337-40 is a 40 dB fixed attenuator designed for RF applications up to 18 GHz. It features SMA female-to-female connectors and operates within a 50 Ohm impedance system. The device is rated for 50 Watts of power handling at the specified attenuation value. Constructed as an in-line module, it provides precise signal reduction for microwave circuits while maintaining signal integrity across its wide frequency range.

Feature Summary

• Provides fixed 40 dB attenuation for signal level control
• Operates effectively from DC to 18 GHz frequency range
• Features SMA female connectors for direct inline integration
• Rated for 50 Watts power handling capability

Applications

• RF test and measurement setups requiring precise signal reduction
• Microwave circuit protection and signal conditioning
• Communication systems needing attenuation between components

Procurement Notes

Verify the specific connector gender configuration matches the design requirement, as SMA variants exist in male/female combinations. Confirm that the 50 Watt power rating aligns with the maximum expected signal levels in the application chain. Ensure the 18 GHz frequency limit covers the operational bandwidth without significant performance degradation or VSWR issues.

Selection Notes

Select this model when a fixed 40 dB reduction is required in a 50 Ohm system operating up to 18 GHz. Consider the SMA interface compatibility with existing cabling and equipment. Evaluate if the 50 Watt power rating suffices for peak and average power conditions. Alternative values such as 30 dB or 50 dB are available if different attenuation levels are needed.

Part Context

This component belongs to Pasternack's line of fixed RF attenuators, which offer various attenuation values and connector types. These devices are engineered for stability and precision in high-frequency environments. The series supports diverse impedance and power requirements, serving as essential passive components for managing signal strength in complex RF architectures.

Replacement Considerations

Direct substitutes include other Pasternack models with identical specifications, such as the PE7337-30 (30 dB) or PE7337-50 (50 dB), if attenuation adjustment is permissible. Cross-manufacturer replacements must match the 40 dB value, 18 GHz limit, 50 Watt rating, and SMA female interface precisely.
