PE7393-30

Overview

The PE7393-30 is a fixed 30 dB attenuator manufactured by Pasternack. It features SMA male to SMA female connectors and operates within a frequency range of 0 Hz to 4 GHz. The device has a power rating of 25 watts and utilizes a black anodized aluminum heatsink body. It maintains a 50 Ohm impedance with a VSWR of 1.15:1. The unit is designed for in-line resistive PI attenuator pad applications.

Feature Summary

• Incorporates a black anodized aluminum heatsink body for thermal management
• Utilizes a resistive PI attenuator pad design for signal attenuation
• Provides fixed 30 dB attenuation between SMA male and female interfaces

Applications

• RF signal control in systems up to 4 GHz
• Signal strength reduction in coaxial circuits
• Test and measurement equipment requiring precise attenuation

Procurement Notes

Verify the specific connector type and attenuation value against project requirements, as datasheet discrepancies exist regarding SMA versus N-type connections and 6 dB versus 30 dB ratings. Confirm the manufacturer is Pasternack and check for RoHS compliance details. Ensure the 25-watt power rating and 4 GHz frequency limit align with system specifications before procurement.

Selection Notes

Select this component when a fixed 30 dB attenuation is required at frequencies up to 4 GHz. The SMA interface suits standard coaxial setups. Consider the 25-watt power handling capability and the heatsink body for thermal dissipation needs. Verify impedance matching at 50 Ohms for system integration compatibility.

Part Context

This part belongs to the Pasternack fixed attenuator series. It is distinct from similar models like PE7389-30 which uses N-type connectors and higher power ratings. The PE7393-30 specifically targets applications requiring SMA connectivity and moderate power handling within the 4 GHz bandwidth.

Replacement Considerations

PE7393-20 offers 20 dB attenuation with identical physical and electrical characteristics except for the decibel value. Other Pasternack SMA attenuators may serve as substitutes if attenuation values differ but interface and frequency specs match.
