Rotary Stepped Attenuator

Annew-Tech’s variable/step attenuator is a 50 Ohm manual step attenuator with attenuation range from 0 to 127dB in 1dB step. It operates DC-18GHz and it rated for 2-10 Watts average RF power. We offer manual rotary attenuators and button attenuators. It is available with 50 Ohm coaxial RF connectors: N, SMA, or 3.5mm Female. These rotary attenuators are also known as variable attenuator or adjustable attenuator.

The rotary step attenuators are allowed for panel mounting.

Rotary variable rf step attenuator can adjust the power level of microwave circuit in step form within a certain frequency range without interrupting the circuit. They have features stable and reliable. Spin life 5000 times for this variable attenuation. Turn gently during use to avoid mechanical deformation such as  loosening and bending of the switch. This manual rotary attenuator aslo named turnable attenuator.
