While an amplifier provides gain, an attenuator provides loss, or gain less than 1. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. It is convenient to discuss them along with decibels. Figure below) The attenuator could be built into the . The calculations for the Pi and T RF attenuator resistor values are relatively straightforward.
However it is often convenient to have a chart that provides the attenuator resistor values in a tabular format.
Model Number, Case Style, F Low (MHz), F High (MHz), Nom. VSWR (:1) DC-5MHz Max. With built-in W power tubes (6Lpower tubes). Attenuation (dB), Flatness (dB) DC-5MHz Typ.
Analog Devices voltage variable attenuators (VVAs) ensure accurate control for a wide range of applications. Our attenuators are available in a low power chip package as well as a 0. The input power ratings range from 0. The terminals of our chip attenuators are made with . Our latest TSseries is compact in size and excellent in frequency response.
RF coaxial attenuators from manufacturer and international supplier Pasternack Enterprises. The wide range of coaxial RF attenuator products from Pasternack are available for same day shipping world wide. By adding an attenuator to the input, you can bring the gain down to dB, and you will be improving the input match.
Browse a wide selection of variable attenuators with digital or analog control, all providing a wide selection of performance in frequency range and robustness. XMA Omni Spectra offers fixed attenuators in many popular and specialty RF coaxial connectors and in many power and frequency ranges. Available from watt up thru 3watts and DC up thru GHz.

Definition of attenuator – a device consisting of an arrangement of resistors which reduces the strength of a radio or audio signal.
Medium Power (- 1Watts) . How do I build an audio pad that meets my exact needs? A dB pad reduces power to one half, dB to one fourth, dB to one tenth, dB to one hundredth, dB to one thousandth and so on. The variable wheel attenuator consists of wheels. Four wheels contain metalized wedged silicon wafers with different attenuation levels and one wheel is empty. If necessary the empty wheel can be filled with a custom element (e.g. filter).
Four attenuators have transmission , , , and. Click on column header to sort).
Engineers are welcome to contact us and we will design a custom flanged attenuator to your exact specifications. Fractional attenuation values available. AlN Note: 2dB to 30dB available.
Special attenuation value requests welcome. However, convention and some literature quote return loss as a negative value akin to an S(1) measurement on a Network analyser. We have device products such as attenuators required for high frequency signal handling.
