PE7357-20

Overview

The Pasternack PE7357-20 is a fixed RF attenuator designed for signal level reduction in microwave systems. It provides a precise attenuation value of 20 dB across a frequency range from 0 Hz to 18 GHz. The component operates with a characteristic impedance of 50 Ohms and supports a maximum power handling capacity of 25 Watts. It features SMA male connectors on both ends, facilitating direct integration into standard RF test setups and communication infrastructure without requiring additional adapters.

Feature Summary

• Provides stable 20 dB signal attenuation across a wide bandwidth up to 18 GHz
• Supports high power handling capability of 25 Watts at rated attenuation
• Utilizes durable SMA male-to-male connector interface for secure mating
• Maintains low voltage standing wave ratio for minimal signal reflection

Applications

• RF test and measurement equipment signal conditioning
• Microwave communication system power leveling
• Laboratory instrumentation input protection
• Wireless base station signal monitoring circuits

Procurement Notes

Verify the specific connector gender configuration matches the target circuit requirements before ordering. Confirm that the operating frequency does not exceed the 18 GHz upper limit to ensure performance integrity. Check environmental specifications if deployment involves extreme temperatures or humidity. Ensure the 25 Watt power rating aligns with peak system signals to prevent component damage during operation.

Selection Notes

Select this model when a fixed 20 dB reduction is required within an 18 GHz bandwidth. Choose this unit over adjustable variants if constant attenuation stability is prioritized. Consider the SMA interface compatibility with existing cabling infrastructure. Evaluate the 25 Watt power rating against maximum expected signal levels to avoid thermal overload during continuous operation.

Part Context

This component belongs to the Pasternack series of fixed attenuators designed for general-purpose microwave applications. It shares the same mechanical form factor and connector style as other models in the family but differs in its specific attenuation value. The design focuses on providing reliable signal reduction without introducing significant phase shift or distortion within the specified frequency range.

Replacement Considerations

Direct substitutes include other manufacturers' 20 dB fixed attenuators with SMA male connectors and 18 GHz bandwidth. Verify that replacement units meet the same 25 Watt power handling requirement. Ensure the substitute maintains comparable VSWR performance to preserve signal integrity in sensitive measurement chains.
