Anong mga uri ng RF coaxial attenuator ang magagamit?

Oras: 2021-11-24 Mga Hit: 8

The coaxial RF attenuators are fabricated by Anritsu, API-Weinschel, API-Inmet, Florida RF Labs, MECA, Radiall, Rosenberger and XMA. It has a wide range of frequencies. The frequency can reach 110GHz. There are two basic types of RF attenuators: fixed and variable. Fixed RF attenuators reduce output signal power relative to input signal power by a fixed amount over a specified bandwidth while the input and output impedances are kept close to the nominal level, usually 50 or 75 Ohms.

While variable RF attenuators use a few different approaches to vary attenuation between two values in a specified range. For example, continuously variable devices vary the attenuation in a continuous fashion. By comparison, RF step attenuators vary the attenuation by only a fixed amount at a time.This is the introduction of the RF attenuator, RF attenuators are widely used in the field of telecommunication equipment.
