PE7488-40

Attenuators Overview

The Pasternack PE7488-40 is a fixed coaxial attenuator designed for RF applications up to 26.5 GHz. It features an SMA male-to-SMA female in-line configuration with a black anodized aluminum body. The component provides a nominal attenuation of 40 dB and is rated for a maximum power handling capacity of 5 Watts. It operates within a frequency range of 0 Hz to 26.5 GHz, maintaining a characteristic impedance of 50 Ohms throughout its operational spectrum.

Attenuators Procurement Notes

Verify the specific model designation PE7488-40 against project requirements to ensure compatibility with 50 Ohm systems and SMA interfaces. Confirm that the 5 Watt power rating and 26.5 GHz frequency limit align with the intended application parameters before finalizing procurement decisions.

Attenuators Selection Notes

Select this component when a fixed 40 dB attenuation value is required within the specified frequency range. Ensure the system impedance matches the 50 Ohm specification and that the connector type (SMA) fits the existing infrastructure. Consider the power handling limits relative to the expected signal levels in the deployment environment.

Attenuators Part Context

This part belongs to the Pasternack series of fixed RF attenuators, which are engineered for stable performance across microwave frequencies. The PE7488-40 specifically addresses needs for significant signal reduction in compact in-line modules, utilizing robust metal construction to maintain electrical integrity and thermal stability during continuous operation.

Attenuators Replacement Considerations

Direct substitutes must match the 40 dB attenuation value, SMA male-to-female interface, and 50 Ohm impedance. Verify that alternative models support the same 26.5 GHz upper frequency limit and 5 Watt power rating to ensure functional equivalence without modification.
