PE11S3911

Overview

The Pasternack PE11S3911 is an SPI-controlled Phase Locked Loop (PLL) frequency synthesizer module designed for radar and RF applications. It operates within a frequency range of 1 GHz to 6.4 GHz, utilizing a 5 Hz step resolution for precise tuning. The device delivers a typical output power greater than +15 dBm. It features SMA connectors for signal interfacing and is housed in a compact module format. This component serves as a stable frequency source for systems requiring wideband coverage and high spectral purity.

Feature Summary

• Integrated SPI interface for digital control and configuration
• Wide frequency coverage from 1 GHz to 6.4 GHz
• High output power exceeding +15 dBm
• Fine frequency resolution with 5 Hz step size

Applications

• Radar system local oscillators
• RF test and measurement equipment
• Wireless communication transceivers
• Signal generation modules

Procurement Notes

Verify the specific ordering suffix and connector type compatibility before integration. Confirm that the SPI protocol matches the host controller's requirements. Ensure the operating environment stays within the specified thermal limits for the module. Check for any required external reference clocks or bias voltages not included in the base module description. Validate regulatory compliance for the intended deployment region.

Selection Notes

Choose this model when a wide bandwidth up to 6.4 GHz is required alongside high output power. The SPI interface simplifies integration into microcontroller-based designs compared to analog alternatives. Consider the module form factor for space-constrained PCB layouts. Evaluate if the 5 Hz step resolution meets the phase noise and spurious requirements of the target application. Compare against lower-frequency models if the upper band is unnecessary.

Part Context

This part belongs to Pasternack's line of RF frequency synthesizer modules. These components are engineered to provide reliable frequency generation for professional and industrial radio frequency applications. The PE11S3911 specifically targets users needing a plug-and-play solution for broadband synthesis without designing discrete PLL circuits from scratch.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Users should consult Pasternack technical support for equivalent models with adjusted frequency ranges or interface protocols. Verify pinout and control logic compatibility when considering alternative suppliers.
