PE11S3909

Overview

The PE11S3909 is an SPI PLL frequency synthesizer module manufactured by Pasternack. It operates within a frequency range of 1 GHz to 6.4 GHz, utilizing SMA connectors for interface. The device provides a +15 dBm output power and supports a frequency step resolution of 20 Hz. Designed for radar applications, it features a chassis or panel mounting type suitable for integration into RF systems requiring precise frequency synthesis capabilities.

Feature Summary

• Integrated SPI control interface for digital programming
• High output power capability at +15 dBm
• Fine frequency resolution with 20 Hz step size
• Dedicated design optimized for radar system applications

Applications

• Radar signal generation
• Frequency synthesis in communication systems
• Test and measurement equipment
• Wireless infrastructure components

Procurement Notes

Verify the specific revision level and connector orientation upon ordering. Confirm that the host system supports the required SPI protocol timing and voltage levels. Ensure thermal management provisions are adequate for continuous operation at maximum output power. Check for any regional export restrictions related to high-frequency RF components before finalizing procurement.

Selection Notes

Select this component when a wide tuning range up to 6.4 GHz is required alongside high output power. Consider the physical dimensions of the SMA connectorized module for enclosure space constraints. Evaluate the need for external filtering if harmonic suppression exceeds internal specifications. Compare against alternative synthesizers if lower phase noise or different control interfaces are necessary.

Part Context

This part belongs to Pasternack's portfolio of active RF modules designed for specialized wireless applications. Unlike passive cable assemblies, it generates signals actively. It complements their broader range of interconnect solutions by providing the source signal rather than just transmission paths. The module integrates the synthesizer circuitry into a standardized form factor for easy system integration.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Alternative selection requires matching the 1-6.4 GHz range, +15 dBm output, and SPI interface. Verify compatibility with existing PCB footprints and SMA connector types when considering generic replacements from other manufacturers.
