2500MHz-2700MHz Direct Digital Synthesizer (DDS) S-Band Signal Source

Product Overview

The 2.5GHz to 2.7GHz DDS Signal Source Module is a precision microwave frequency synthesizer designed for high-frequency applications. Operating in the critical S-band, this module provides highly accurate and flexible signal generation via Direct Digital Synthesis (DDS) technology.

Equipped with an RS485 communication interface, the module allows for seamless integration into complex systems where remote frequency and power adjustments are required. It is an excellent choice for 4G/LTE band testing, satellite communication simulation, and signal interference systems.

Key Features

• S-Band Precision: Optimized for the 2500MHz to 2700MHz range with high frequency stability.

• Advanced Sweeping Capabilities: Supports both point frequency and multi-segment sweeping. Users can program up to 8 independent frequency segments.

• Dynamic Power Control: Offers a 31.5dB dynamic range with a fine 0.5dB adjustment step for precise signal leveling.

• Programmable Flexibility: The dedicated software allows for real-time querying and configuration of frequency limits, power levels, and minimum step intervals.

• Industrial Reliability: Features a wide input voltage range (DC 12V-29V) and a robust 7W2 connector for power and control.

Technical Specifications

Applications

• S-Band Communication Testing: Ideal for testing components used in WiMAX, LTE (Band 7/38/41), and specialized satellite links.

• Electronic Countermeasures: Used as a reliable signal source for narrow-band interference and jamming equipment.

• Automated Production Lines: Easily integrated into ATE (Automated Test Equipment) environments via RS485.

• Signal Simulation: Generates accurate S-band signals for laboratory research and development.

Control & Configuration

The module’s intelligence is managed through the RS485 control protocol. Users can:

1. Individually Enable Segments: Control each of the 8 frequency segments independently.

2. Fine-Tune Resolution: Set the minimum step interval to meet specific bandwidth requirements.

3. Real-Time Monitoring: Query the module to confirm current operating parameters and power status.
