PE7055-40

Overview

The Pasternack PE7055-40 is a fixed RF attenuator designed for high-power applications. It provides a nominal attenuation of 40 dB with a frequency range extending from 0 Hz to 18 GHz. The component utilizes TNC male-to-female connectors and operates within a 50 Ohm impedance system. It is rated for a maximum power handling capacity of 50 Watts at the specified attenuation value. The housing is constructed from directional aluminum with a black anodized finish, ensuring thermal stability and durability in demanding environments.

Feature Summary

• High power handling capability rated at 50 Watts
• Broadband operation up to 18 GHz
• Durable directional aluminum heatsink body
• Black anodized surface finish

Applications

• RF signal level control in microwave systems
• Test and measurement equipment calibration
• Communication infrastructure signal attenuation
• Radar system component integration

Procurement Notes

Verify the specific connector gender configuration (TNC Male to Female) matches your system requirements. Confirm that the 50 Watt power rating aligns with your operational peak power levels. Ensure the 18 GHz frequency range covers your intended application spectrum. Check for any environmental specifications regarding the anodized finish if operating in harsh conditions.

Selection Notes

Select this model when high power dissipation is required alongside precise 40 dB attenuation. The TNC interface suits applications needing robust mechanical connections. Consider the physical size of the aluminum heatsink for enclosure space planning. Verify compatibility with existing TNC mating connectors in the signal chain.

Part Context

This component belongs to Pasternack's line of fixed attenuators, specifically engineered for microwave frequencies. It serves as a passive device to reduce signal amplitude without distortion. The PE70 series typically focuses on high-power tolerance and wide bandwidth capabilities for industrial and defense applications.

Replacement Considerations

Direct substitutes must match the 40 dB attenuation value, 50 Ohm impedance, and TNC connector type. Ensure replacement parts support the same 50 Watt power rating and 18 GHz frequency limit. Physical dimensions and mounting style should be compatible with existing setups.
