Rotary Step Attenuators

Variable Stepped Rotary Attenuators

Narda-MITEQ now supplies a limited line of Rotary Step Attenuators to compliment our wide variety of Microwave RF Continuously Variable Attenuators.

Narda-MITEQ Rotary Stepped Attenuators have 1dB or 10dB steps, 30 degrees with stops at minimum and maximum. Most Narda-MITEQ step attenuator models can be supplied with SMA, Type-N or BNC connectors.

Coaxial rotary attenuators are manufactured with frequency ranges from DC-2500 MHz with low insertion loss and VSWR from 1.2:1 to 1.5:1 depending on the model.

Please call us with your rotary stepped attenuator requirements and discuss your needs with one of our design engineers.
