PE7321-40

Overview

The PE7321-40 is a fixed RF attenuator manufactured by Pasternack. It provides an attenuation value of 40 dB across a frequency range from 0 Hz to 18 GHz. The device operates with a characteristic impedance of 50 Ohms and supports a maximum power handling capacity of 50 Watts. This component utilizes a resistive PI attenuator pad design for signal reduction.

Feature Summary

• Fixed 40 dB attenuation level
• Wideband operation up to 18 GHz
• Resistive PI network topology

Applications

• RF signal level control in microwave systems
• Test and measurement equipment calibration
• Signal conditioning in communication networks

Procurement Notes

Verify the specific connector configuration against project requirements, as datasheets may list variations such as 7/16 DIN or Type-N interfaces. Confirm that the 50W power rating aligns with system thermal constraints. Ensure the 18 GHz frequency limit meets bandwidth needs. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and availability.

Selection Notes

Select this model when a precise 40 dB reduction is required within an 18 GHz bandwidth. The 50W power handling makes it suitable for high-power applications compared to lower-rated alternatives. Consider the physical interface compatibility, such as 7/16 DIN or N-type connectors, to match existing cabling infrastructure without requiring additional adapters.

Part Context

This component belongs to Pasternack's line of fixed RF attenuators designed for microwave and radio frequency applications. These devices are engineered to provide stable attenuation values with minimal insertion loss variation over the specified frequency range. The product series typically includes various attenuation levels and power ratings to suit different system architectures.

Replacement Considerations

Direct substitutes include other 40 dB fixed attenuators from Pasternack with compatible interfaces, such as the PE7321-50 which offers 50 dB attenuation but shares similar structural characteristics. Verify that any replacement maintains the 50 Ohm impedance and 50W power handling capabilities to ensure system integrity.
