PE7063-20

Overview

The PE7063-20 is a fixed DC bias attenuator manufactured by Pasternack, designed for in-line RF signal conditioning. It provides a precise attenuation value of 20dB within a frequency range of 500 MHz to 2 GHz. The component utilizes a resistive PI attenuator pad design and operates at a power rating of 2 Watts. It features TNC male to TNC female connectors and is housed in a passivated stainless steel body, ensuring durability and consistent 50 Ohm impedance performance.

Feature Summary

• Incorporates a resistive PI attenuator pad design for stable signal reduction
• Supports DC bias transmission through the attenuator path
• Constructed with a passivated stainless steel body for environmental resistance

Applications

• Radar systems
• RF test and measurement instrumentation
• Prototyping and characterization setups

Procurement Notes

Verify that the specific order matches the PE7063-20 part number to ensure correct TNC connector gender configuration and 20dB attenuation value. Confirm the requirement for passivated stainless steel construction aligns with project specifications. Ensure compatibility with 50 Ohm system impedance and 2 Watt power handling limits before integration into the final assembly.

Selection Notes

Select this model when a fixed 20dB loss is required between 500 MHz and 2 GHz with DC bias capability. Choose over other variants if TNC inline connectivity is mandatory rather than SMA or BNC options. Consider the 2 Watt power rating against expected signal levels to prevent thermal issues. Verify that the stainless steel housing meets corrosion resistance requirements for the intended environment.

Part Context

This component belongs to Pasternack's series of coaxial DC bias attenuators. It shares the core PI pad topology with models like PE7061-20 but differs in connector type. Unlike the brass nickel PE7000-20, this unit offers stainless steel construction. It serves as a specialized passive device for maintaining signal integrity while allowing control voltage passage in RF chains.

Replacement Considerations

Direct substitutes include PE7061-20 for SMA connections or PE7449-20 for tri-metal brass bodies. Ensure replacement parts maintain the same 20dB attenuation and 2W power rating. Verify that alternative connector types fit the existing mechanical interface without adapter usage.
