Micro Harmonics Launches mmWave Voltage-Variable Attenuator Based on Faraday Rotation Technology

Micro Harmonics Corporation, a recognized innovator in high-frequency RF and microwave solutions, has launched its newest millimeter-wave voltage-variable attenuator (VVA) that harnesses Faraday rotation technology. The WR-8 VVA is optimized for systems operating in the 90-140 GHz frequency range, delivering full band performance. It offers system designers a transformative tool for high-performance signal management where traditional PIN-diode or resistive attenuators fall short. 

Key Advantages and Specifications:

1. Low Loss: < 1.0 dB average insertion loss across the full band
2. Fast, Long-Lasting Electrical Tuning: Voltage-controlled Faraday rotation enables rapid electrical tuning with no moving parts to wear out
3. Compact Formfactor: Compact size enables easy integration into electrical systems
4. Flexible Integration: Available in WR-6.5, WR-8, and WR-10 waveguide configurations
5. ESD insensitive
6. High power handling capability: 2.4 W
7. Low VSWR

Each unit is fully characterized on a vector network analyzer, and the data is provided to the customer.
