FMSN3901

Overview

The FMSN3901 is a USB Frequency Synthesizer utilizing Phase Locked Loop (PLL) technology, manufactured by Fairview Microwave. It operates within an output frequency range of 25 MHz to 6 GHz and requires a 20 MHz reference input signal. The module delivers an output power of -17 dBm with a phase noise specification of -86 dBc/Hz at the SMA interface. Designed for robust performance, it functions within a temperature range of 0°C to +55°C and draws a typical operating supply current of 470 mA.

Feature Summary

• Generates stable RF signals across a wide microwave frequency spectrum using integrated PLL architecture
• Provides low phase noise performance suitable for high-fidelity signal generation applications
• Features standard SMA connectors for straightforward integration into existing RF test setups
