PE7203-40

Overview

The Pasternack PE7203-40 is a fixed 40 dB attenuator designed for high-power RF applications. It features a 50 Ohm impedance and operates from DC to 6 GHz. The unit utilizes an in-line, resistive PI attenuator pad design with 7/16 DIN male connectors on both ends. It supports a maximum power handling of 100 Watts and maintains a maximum VSWR of 1.45:1. Constructed with hexagonal in-line module housing, it weighs approximately 1.36 kg.

Feature Summary

• High power handling capability up to 100 Watts
• Wideband frequency operation from DC to 6 GHz
• Robust 7/16 DIN male connector interface
• Resistive PI attenuator pad design

Applications

• RF signal level reduction in high-power transmission lines
• Test and measurement setups requiring precise attenuation
• Base station and wireless infrastructure testing
• Amplifier output power monitoring and control

Procurement Notes

Verify the specific connector gender and orientation against your system requirements before purchase. Confirm that the 100W power rating aligns with your peak signal levels. Ensure the 7/16 DIN interface matches existing cabling. Check for any specific environmental ratings if used outdoors.

Selection Notes

Select this model when a fixed 40 dB attenuation value is required within the 6 GHz bandwidth. Consider the physical size and weight due to the heavy-duty construction. Compare with adjustable alternatives if variable attenuation is needed later. Ensure the 50 Ohm system impedance matches your network.

Part Context

This component belongs to Pasternack's line of fixed coaxial attenuators. It is part of the PE7203 series, which offers various attenuation values. These units are engineered for durability and consistent performance in demanding RF environments. The series provides standardized interfaces for easy integration into existing test fixtures.

Replacement Considerations

Direct substitutes include other 40 dB fixed attenuators with 7/16 DIN male connectors and similar power ratings. Verify frequency range compatibility up to 6 GHz. Check for equivalent VSWR specifications to ensure minimal signal reflection. Alternative models may vary in physical dimensions or mounting style.
