PE7035-2

Overview

The PE7035-2 is a 0 to 10 dB rotary step attenuator designed for 75 Ohm RF systems. It features BNC Female connectors and provides attenuation in 1 dB steps from 0 to 10 dB. The device operates from DC to 500 MHz with a maximum input power rating of 1 Watt. It utilizes a rotary control mechanism for precise adjustment and maintains a VSWR of 1.25:1 across its frequency range.

Feature Summary

• Rotary step control mechanism for adjustable attenuation
• 75 Ohm impedance matching for specialized RF applications
• BNC Female connector interface on both ports

Applications

• 75 Ohm RF signal testing and measurement setups
• Cable television (CATV) system signal level adjustment
• Broadcast equipment signal attenuation and balancing

Procurement Notes

Verify the specific connector gender configuration, as sources indicate potential variations between BNC and TNC types for this model number. Confirm the impedance rating matches the 75 Ohm requirement for your specific application before procurement. Ensure the rotary step functionality aligns with your control interface needs.

Selection Notes

Select this component when working within 75 Ohm RF environments requiring manual, step-wise signal reduction up to 10 dB. It is suitable for frequencies up to 500 MHz. Consider the 1 Watt power handling limit for high-power applications. Verify connector compatibility if interfacing with standard 50 Ohm systems using appropriate adapters.

Part Context

This part belongs to Pasternack's line of coaxial RF attenuators. It serves as a passive component for managing signal strength in radio frequency circuits. The rotary design distinguishes it from fixed or digital step attenuators, offering manual adjustability for laboratory or field adjustments.

Replacement Considerations

Direct substitutes may include other 75 Ohm rotary step attenuators with similar BNC interfaces. Verify that any replacement matches the 0-10 dB range, 500 MHz frequency limit, and 1 Watt power rating. Cross-reference connector types to ensure mechanical compatibility.
