PE7311-40

Overview

The Pasternack PE7311-40 is a fixed RF attenuator module designed for high-power applications. It provides a nominal attenuation of 40 dB with an impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 7.5 GHz and is rated for 50 Watts of power at the stated attenuation value. The unit features N Female to 7/16 DIN Male connectors, ensuring compatibility with standard microwave interconnect systems.

Feature Summary

• High power handling capability rated at 50 Watts
• Wideband operation extending up to 7.5 GHz
• Fixed 40 dB attenuation value
• Mixed connector interface combining N Female and 7/16 DIN Male terminals

Applications

• Microwave signal conditioning in test and measurement setups
• RF power monitoring circuits requiring precise attenuation
• Communication system component protection
• Laboratory equipment interfacing

Procurement Notes

Verify the specific connector orientation and gender configuration against your schematic requirements before ordering. Confirm that the 50 Watt power rating aligns with your maximum operational signal levels to prevent damage. Ensure the 7.5 GHz frequency limit covers your entire bandwidth needs. Check for any specific mounting or thermal management requirements associated with the module form factor.

Selection Notes

Select this model when a fixed 40 dB reduction is required in a 50 Ohm system. Consider the mixed connector types (N Female to 7/16 DIN Male) as a primary selection criterion for interface compatibility. Evaluate the 50 Watt power rating against peak and average power levels. Compare the 7.5 GHz upper frequency limit with your application's spectral requirements to ensure adequate performance margins.

Part Context

This component belongs to Pasternack's line of fixed RF attenuators, which are passive devices used to reduce signal amplitude without distortion. These modules are typically constructed using precision resistive elements housed in robust metal enclosures to maintain impedance stability and thermal dissipation capabilities across the specified frequency range.

Replacement Considerations

Direct substitutes must match the 40 dB attenuation, 50 Ohm impedance, and 50 Watt power rating. Connector combinations must be identical (N Female to 7/16 DIN Male). Frequency response should ideally meet or exceed 7.5 GHz. Verify physical dimensions and mounting styles if space constraints exist.
