Pasternack RF Coaxial attenuators

Pasternack range of RF coaxial attenuators include continuously variable attenuators, DC bias attenuators, fixed attenuators and step attenuators models. These RF attenuators are available in 50 Ohm and 75 Ohm impedance variations. There series of coaxial attenuators are available in 2.4mm, 2.92mm, 7/16 DIN, 7mm, BNC, F, N, SMA and TNC connectors. RF dB attenuation values for these Pasternack attenuators range from 0 dB to 110 dB. The frequency range of Pasternack RF attenuators is from DC to 50 GHz. This product line includes low to high power attenuators which have power handling that ranges from 0.5 Watts to 500 Watts.

Pasternack RF coaxial attenuators include male and female genders and can be bi-directional and directional, depending on the power rating. There RF attenuators are manufactured to precise industry specifications and the bodies are constructed of an aluminium finned heatsink, stainless steel or nickel plated brass. Pasternack uses Pi attenuators or Pi pads for its inline RF attenuator designs.
