PE11S3904

Overview

The Pasternack PE11S3904 is a USB PLL frequency synthesizer designed for signal conditioning applications. It operates within the 21 GHz to 24 GHz output frequency range, delivering a power output of -17 dBm. The device utilizes a 50 MHz reference input and features an SMA output connector interface.

Feature Summary

• Integrates a phase-locked loop architecture for stable frequency generation
• Provides direct USB connectivity for digital control and configuration
• Delivers consistent RF output power across the designated millimeter-wave spectrum

Applications

• Radar system development and testing
• Millimeter-wave communication equipment
• Signal integrity analysis in high-frequency circuits

Procurement Notes

Verify the specific firmware version and USB protocol compatibility with your host system before integration. Confirm that the required 50 MHz reference source meets the stability specifications outlined in the official datasheet. Ensure proper shielding is implemented to maintain signal integrity at the 21 GHz to 24 GHz operating frequencies during deployment.

Selection Notes

Select this component when a compact, digitally controlled solution is required for generating precise signals in the 21 GHz to 24 GHz band. The integrated USB interface simplifies control logic compared to discrete analog synthesizers. Consider the -17 dBm output level to determine if additional amplification is necessary for your specific application path.

Part Context

This unit belongs to Pasternack's portfolio of active RF modules and ICs. It serves as a complete signal conditioning solution, combining synthesis and output stages into a single form factor.
