Microwave communication requires the usage of active devices and passive devices of multiple kinds. One such passive device is Attenuator. Used for reducing the power of a signal, attenuator is made from simple voltage divider networks. You will find use of attenuators in instruments that involve transmission, control, or measurement of microwave energy. Opposite of amplifiers, attenuators when added to the input, bring down the gain and improve the input match. Known for weakening the high level output of a signal generator, attenuators can built to be a stand-alone device or built into the signal generator. In microwave systems, coaxial attenuators are used in transmitters and receivers. Moreover, in this application area, amount or range of attenuation, flatness with frequency, average & peak power-handling capability, temperature characteristics and size & weight of attenuators are considered.

Now, lets talk about the different types of attenuators. Variable and fixed, attenuators can be availed in two categories. Variable attenuators are good for applications, where accuracy is not that important. These find a vast usage where it is important to constantly vary the level of a signal. For system, OEM and laboratory applications, variable attenuators are categorized into lossy wall, variable coupler, low loss cutoff, step (or turret) and voltage-controllable sections. Where on the other hand, fixed attenuators are different. Fixed attenuators are associated with accuracy. These have a specific value and can't be changed. For system applications, fixed attenuators are used for two categories of service. The first one is in calibration channel to establish a known signal level (here, flatness over the required frequency range is prominent) and in the second, the device is used like a buffer to avoid interaction between two devices, or for impedance matching (here, low VSWR is important).

Looking for offer for microwave attenuators? Find reputed online websites that deal in the passive microwave components, manufactured from quality-grade material. And you can avail different types from there. Made available in several specifications in the market, high quality fixed attenuator online can be purchased from stores that offer reasonable prices for the same, Although, you need to be sure of your requirements and then, purchase the correct attenuator. You may find that fixed attenuators are available in a series of formats, right from small in-line items, in a matching format to connector adaptors, to those incorporated within equipments, to the ones in small boxes with connectors on the ends.

You can read more about attenuators and their functionality in other articles and blogs, which emphasize on the device in much more detail.
