A Fixed Coaxial Attenuator is a 2-port coaxial RF interconnect device that attenuates the RF signal passing through it by a prescribed amount (e.g., 1dB, 2dB, 3dB). Sometimes used in the field in larger communications systems, these devices are mostly found in Test and Measurement applications—including both laboratory and factory testing environments. Most of these attenuator devices have 50 ohms of nominal impedance, but others are available for cable TV applications with 75 ohms impedance.Also included in this product line are “impedance matching pads,” which convert between 50 and 75 ohms while providing a set amount of RF attenuation.
Richardson RFPD / Arrow RF & Power carries a large assortment of Fixed Coaxial Attenuators. These products, taken as a group, cover the complete frequency range from 0 MHz (DC) to 50 GHz and provide from 0 to 60 dB of precision RF signal attenuation. Some models can handle up to 300 Watts of RF signal power.
Specific attributes which are important in selecting the right Fixed Coaxial Attenuator for your application include the Connector Type (SMA, BNC, etc.), the amount of Attenuation provided (in dB), and the Maximum Frequency (GHz) of operation for the device.
Richardson RFPD offers an extensive selection of Fixed Coaxial Attenuators from industry-leading manufacturers Aeroflex/Inmet, HUBER+SUHNER, Radiall and SV Microwave.
The parametric search filter allows the user to quickly find the parts they need by filtering the results in real-time.
Additionally, some attributes allow for the conversion of their base type to different types. For example, the attribute group for minimum frequency is shown in MHz. The values can be converted to be shown in KHz or GHz by selecting the conversion type from the ‘Select Conversion’ drop down list.
Any Attribute that does not interest the user can be hidden by clicking on the ‘X” in the upper-right corner of the attribute. To show any hidden attributes, simply click the ‘Unhide Attributes’ button in the bottom of the parametric search filter.
If you are experiencing performance issues, please use a newer browser such as Chrome or Firefox, or disable the ability of the filter to perform dynamic updates by deselecting the checkbox titled ‘Allow Filters to Dynamically Update Parametric Search Attributes’.
