What is an Attenuator?
An attenuator is an electronic device which reduces the amplitude or power of a signal without causing a big distortion to its waveform. An attenuator is the opposite of an amplifier. While an amplifier provides gain, an attenuator provides a gain less than 1, or a loss. Attenuators are passive devices which are made using simple voltage divider networks. It is a circuit which suppresses or opposes a specific frequency band and is used for filtering and reducing noise in a circuit. Radio frequency or RF attenuators are coaxial in structure. Attenuation is expressed in decibels of relative power.
Types of Attenuators
There are several different kinds of programmable attenuators at Future Electronics. We stock many of the most common types categorized by several parameters including input power, operating frequency, operating temperature range, maximum conversion loss and packaging type. Our parametric filters will allow you to refine your search results according to the required specifications.
Attenuators from Future Electronics
Future Electronics has a wide range of programmable attenuators from several manufacturers that can be used for a programmable, wireless, rf, voltage variable, power, step, coaxial (coax), audio, voltage controlled or stepped attenuator. Once you decide if you need digital attenuators, passive attenuators or variable attenuators, you will be able to choose from their technical attributes and your search results will be narrowed to match your specific attenuator application needs.
We deal with several manufacturers such as Hittite Microwave, IRC, Johanson Manufacturing Corp or Vishay, among others. You can easily refine your attenuator product search results by clicking your preferred attenuator brand from the list of manufacturers below.
Applications for Attenuators:
Fixed attenuators in circuits are used to dissipate power, lower voltage as well as in improving impedance matching. Attenuator pads or adaptors are used in measuring signals in order to lower the amplitude of the signal by a known amount in order to enable measurements or to protect the measuring device from signal levels that could damage it.
Choosing the Right Attenuator:
With the FutureElectronics.com parametric search, when looking for the right attenuators, you can filter the results by category. We carry the following categories of attenuators:
- Digital attenuators
- Passive attenuators
- Variable attenuators
Once you choose the attenuator category, you can narrow them down by various attributes: by input power, operating frequency, operating temperature range and maximum conversion loss to name a few. You will be able to find the right attenuator for a wireless, rf, programmable, step, voltage variable, coaxial (coax), audio, power, stepped or voltage controlled attenuator using these filters.
Attenuators in Production Ready Packaging or R&D Quantities
If the quantity of attenuators you require is less than a full reel, we offer to our customers several of our programmable attenuators in tray, tube or individual quantities that will help you avoid unneeded surplus.
Future Electronics also offers its clients a unique bonded inventory program designed to eliminate potential problems that may arise from an unpredictable supply of products that could contain raw metals and products with erratic or long lead times.
