PE11S3901

Overview

The PE11S3901 is a USB PLL frequency synthesizer module manufactured by Pasternack. It operates within a frequency range of 25 MHz to 6 GHz and utilizes a 50 MHz reference input. The device provides an output power greater than -40 dBm through an SMA connector interface. Key technical specifications include a step size ranging from 12.5 MHz to 100 MHz and harmonic suppression levels between -34.5 dBc and higher values.

Feature Summary

• Integrates Phase Locked Loop (PLL) technology for stable frequency synthesis
• Connects via Universal Serial Bus (USB) for digital control and configuration
• Provides SMA female output interface for RF signal transmission

Applications

• Radar system testing and development
• UHF and VHF instrumentation
• General-purpose RF signal generation

Procurement Notes

Verify the specific datasheet version when sourcing this component, as revision changes may affect pinout or firmware compatibility. Confirm that the host system supports the required USB communication protocol. Ensure environmental conditions match the operational limits specified in the official documentation before integration into final assemblies.

Selection Notes

Select this module when a wide tuning range up to 6 GHz is required with precise frequency stepping capabilities. The integrated USB interface simplifies control logic compared to discrete synthesizer chips. Consider the SMA output impedance matching requirements for downstream components. Evaluate the phase noise performance against specific application sensitivity thresholds.

Part Context

This component belongs to Pasternack's line of USB-controlled RF modules designed for laboratory and industrial test environments. It serves as a compact alternative to benchtop synthesizers, offering portability without sacrificing frequency coverage. The module integrates necessary control electronics and voltage regulation within a single enclosure.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific model. Direct replacements require matching the USB control protocol, frequency range, and output power specifications exactly.
