Byonics

Our passive step attenuators have 4 indepenently selectable attenuation stages of 5dB, 10dB, 20dB and 30dB. By enabling these stages, attenuation levels between 0dB and 65dB can easily be selected.

Passive Attenuators are Signal Reducing Resistive Networks

Passive attenuators are purely passive resistive network (hence no power supply) that can be used in a wide variety of electronic equipment to reduce the strength of the signal passing through it.

Passive Attenuator Tutorial and Resistive Attenuator Designs

The Passive Attenuator is a purely resistive network that is used to weaken or “attenuate” a signal level without using an external power source. This makes passive attenuators the opposite of amplifiers.

Passive Attenuator, working, uses, Applications, Advantages

The passive attenuator decreases power provided to connected load through a single fixed value, variable quantity, or in a series of known switchable steps. Attenuators are used in

Attenuator Circuit Designs: Passive to Programmable

Passive attenuators use resistor networks for signal reduction without power, while active attenuators can include components like MOSFETs and PIN diodes for adjustable attenuation levels.

Manually Variable Attenuators

Manually controlled variable attenuators are passive devices that require no external power source to operate. A majority of our models have rotary knobs for manual control.
