Programmable RF Attenuator 0.1–40 GHz with Digital Control
The LDA-403 from VAUNIX is a precision programmable RF attenuator covering frequencies from 0.1 to 40 GHz. With USB and Ethernet connectivity, this digitally controlled attenuator offers flexible attenuation adjustment for laboratory testing, system integration, and automated measurement applications across sub-microwave through mmWave bands.
Technical Specifications
- Frequency Range: 0.1–40 GHz
- Attenuation Range: 31.5 dB maximum
- Step Resolution: 0.5 dB for precise signal level control
- Connector Type: 2.92 mm interface
- Control Interfaces: USB and Ethernet for remote programming and automated test sequences
- Operation: Fully programmable, eliminating manual switching
Application Areas
- 5G/6G & Telecommunications: Power level conditioning for sub-6 GHz and mmWave frequency testing in component and subsystem validation
- SATCOM & Defense: Signal simulation, system performance verification, and threat environment emulation for aerospace and military platforms
- Laboratory & ATE Systems: Integration with automated test equipment requiring repeatability, traceability, and coordinated multi-channel operation
- Component Testing: Amplifier characterization, LNA linearity testing, gain measurement, and noise figure assessment
The programmable architecture reduces setup time and human error in complex measurement procedures. Both USB and Ethernet interfaces enable straightforward integration into standalone and networked test configurations, supporting single-instrument deployments as well as synchronized multi-channel systems.
