PE8739A

Overview

The PE8739A is a combline bandpass filter manufactured by Pasternack, designed for S-band and C-band applications. It features SMA female connectors and operates within a frequency range of 4.4 GHz to 4.8 GHz, providing a 400 MHz passband with a center frequency of 4.6 GHz. The unit exhibits an insertion loss of 1.25 dB and utilizes a threaded mechanical design. It functions reliably in temperatures ranging from -30°C to 70°C.

Feature Summary

• Combline architecture optimized for S-band and C-band performance
• Threaded mechanical construction for secure installation
• SMA female connector interface

Applications

• S-band radio frequency systems
• C-band communication infrastructure
• Signal conditioning requiring specific bandpass filtering

Procurement Notes

Verify the exact operating frequency range and insertion loss specifications against the official datasheet before integration. Confirm that the SMA female connector type matches your system requirements. Ensure environmental conditions remain within the specified -30°C to 70°C operational temperature limits for reliable performance.

Selection Notes

Select this component when a fixed 400 MHz bandwidth centered at 4.6 GHz is required. The threaded design suits applications needing robust mechanical stability. Verify compatibility with existing SMA interfaces and ensure the insertion loss of 1.25 dB meets system signal integrity budgets.

Part Context

This part belongs to Pasternack's line of microwave and RF filters. It is distinct from their coaxial connectors and adapters, serving specifically as a passive signal conditioning device. The combline design differentiates it from cavity or microstrip filter technologies.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify if other Pasternack models offer similar center frequencies and bandwidths if replacement is necessary.
