PE7161-10

Overview

The PE7161-10 is a fixed bidirectional attenuator manufactured by Pasternack Enterprises. It features SMA male to SMA female connectors and a brass tri-metal body. The device provides 10 dB attenuation with an accuracy of ±1.5 dB. It operates from DC to 2 GHz at a 50 Ohm impedance. Maximum input power is rated at 1 Watt, with a maximum VSWR of 1.2:1. Operating temperature ranges from -20°C to +85°C. Physical dimensions are 0.98 inches in length and 0.312 inches in width.

Feature Summary

• Bidirectional signal attenuation capability
• SMA connector interface configuration
• Brass tri-metal body construction

Applications

• RF signal level reduction
• Impedance matching between circuits
• Test and measurement setups

Procurement Notes

Verify the specific model suffix against official Pasternack documentation to confirm connector gender and material specifications. Ensure the operating frequency range up to 2 GHz aligns with system requirements. Confirm that the 1 Watt power rating is sufficient for the intended application environment. Check for compliance with relevant industry standards such as MIL-STD-348 if required for the specific deployment scenario.

Selection Notes

Select this component when a fixed 10 dB attenuation value is required within the DC to 2 GHz frequency band. Consider the SMA connector type for compatibility with existing test equipment or circuit boards. Evaluate the 1 Watt power handling capacity against peak signal levels. The compact mechanical size facilitates integration into space-constrained RF assemblies requiring precise signal control.

Part Context

This part belongs to the Pasternack fixed attenuator series, designed for reliable RF signal management. It utilizes standard SMA interfaces common in microwave applications. The brass tri-metal body provides durability and consistent electrical performance across the specified temperature range. It serves as a passive component for controlling signal amplitude in communication systems.

Replacement Considerations

Cross-reference with other Pasternack models offering similar attenuation values and connector types. Verify that substitute parts maintain the same DC to 2 GHz frequency range and 50 Ohm impedance. Ensure replacement components meet the 1 Watt power rating and physical dimension constraints for direct interchangeability.
