TUNEFUL CORPORATION RF manufactures several basic models of Voltage Variable Microwave Attenuators, widely used in the industry. PIN diode-based they provide high efficiency and relatively low cost with attenuation up to 30 or 50 dB depending on the model. Adjustment is being done by changing voltage level.
In the below table you may find the standard models of Voltage Controlled Microwave Attenuators. We are also ready to review your request for customized product fitting your needs best of all, please, feel free to contact us.
