Overview
The Pasternack PE7044-3 is a fixed RF attenuator designed for 75 Ohm systems. It provides a precise attenuation value of 3 dB across a frequency range of 0 Hz to 4 GHz. The component utilizes N-Type connectors, featuring a male interface on one side and a female interface on the other. It is rated for a maximum power handling capacity of 2 Watts at the specified attenuation level. The unit operates within a temperature range of -65°C to +165°C. Construction involves brass components with a nickel finish.
Feature Summary
- Provides stable 3 dB signal reduction in 75 Ohm transmission lines
- Operates effectively from DC up to 4 GHz frequency range
- Supports continuous power loads up to 2 Watts
- Features robust N-Type connector interfaces for secure integration
Applications
- Signal level adjustment in 75 Ohm video distribution networks
- Impedance matching and reflection control in broadcast infrastructure
- Test and measurement setups requiring precise signal attenuation
- RF circuit protection by reducing input power levels
Procurement Notes
Verify that the specific procurement order matches the 75 Ohm impedance requirement, as standard 50 Ohm variants exist within the same product family. Confirm the connector gender configuration aligns with system design needs. Ensure environmental specifications meet operational temperature requirements. Cross-reference datasheet revisions to confirm material composition and plating details. Validate supplier authenticity through authorized channels to guarantee component performance integrity.
Selection Notes
Select this model specifically for applications requiring 75 Ohm impedance compatibility rather than the more common 50 Ohm standard. Consider the 2 Watt power rating when designing circuits with high signal strength. Evaluate the N-Type connector size and mating force against existing hardware constraints. Assess thermal management capabilities given the wide operating temperature range. Compare attenuation tolerance specifications against system sensitivity requirements to ensure adequate signal control precision.
Part Context
This component belongs to Pasternack's line of fixed RF attenuators, which offer various attenuation values and impedance options. The PE7044-3 specifically addresses the niche market for 75 Ohm microwave and radio frequency applications. It complements other models like the PE7044-6 and PE7044-10, providing different attenuation steps while maintaining consistent connector types and power ratings across the series.
Replacement Considerations
Direct substitutes include other 3 dB fixed attenuators with 75 Ohm impedance and N-Type connectors. Verify that alternative models maintain the same 4 GHz frequency limit and 2 Watt power rating. Check for identical physical dimensions to ensure mechanical fit within existing assemblies. Confirm that replacement units offer comparable VSWR performance and attenuation accuracy.
