Micro Harmonics launches its newest millimeter-wave voltage-variable attenuator (VVA) that harnesses Faraday rotation technology. The WR-8 VVA is optimised for systems operating in the 90-140GHz frequency range, delivering full band performance.
This product offers system designers a transformative tool for high-performance signal management where traditional PIN-diode or resistive attenuators fall short.
Among its key specifications are:
-
Low Loss: < 1.0 dB average insertion loss across the full band;
-
Fast, Long-Lasting Electrical Tuning: Voltage-controlled Faraday rotation enables rapid electrical tuning with no moving parts to wear out;
-
Compact Formfactor: Compact size enables easy integration into electrical systems;
-
Flexible Integration: Available in WR-6.5, WR-8, and WR-10 waveguide configurations;
-
ESD insensitive;
-
High power handling capability: 2.4 W;
-
Low VSWR.
Each unit is fully characterized on a vector network analyzer, and the data is provided to the customer.
