PE7057-2

Overview

The Pasternack PE7057-2 is a fixed RF attenuator designed for signal level reduction in coaxial systems. It provides a nominal attenuation of 2 dB with an operating frequency range from DC to 1 GHz. The component features a 75 Ohm impedance and utilizes F-type female connectors on both input and output ports. It is rated for a maximum power handling capacity of 2 Watts, ensuring reliable performance in standard broadcast and communication applications requiring precise signal attenuation within the specified frequency band.

Feature Summary

• Provides fixed 2 dB attenuation for consistent signal reduction
• Designed for 75 Ohm impedance systems using F-type connectors
• Operates effectively across a DC to 1 GHz frequency range

Applications

• Broadcast signal distribution networks
• Cable television (CATV) infrastructure
• RF test and measurement setups

Procurement Notes

Verify that the target system operates at 75 Ohm impedance, as this component is incompatible with standard 50 Ohm environments. Confirm that the required attenuation value of 2 dB aligns with the design specifications. Ensure the operating frequency does not exceed 1 GHz and that the signal power remains within the 2 Watt rating to prevent damage or performance degradation during installation.

Selection Notes

Select this model when a fixed, low-value attenuation is required for 75 Ohm F-type interfaces. It is suitable for applications where variable adjustment is unnecessary and precise, stable signal reduction is critical. Consider the physical form factor and connector orientation to ensure compatibility with existing rack or panel mounting requirements in the specific deployment environment.

Part Context

This component belongs to the Pasternack RF Attenuators product line, which offers various fixed, step, and continuously variable models. The PE7057-2 specifically addresses the niche requirement for 75 Ohm systems, distinguishing it from the manufacturer's more common 50 Ohm offerings. It serves as a passive interconnect device essential for maintaining signal integrity in specialized broadcast and video transmission architectures.
