Attenuators, Bias-Ts, & Terminations
Fixed | Variable | Programmable)
Manufacturers & Services

The companies listed here can supply your needs for any type of attenuator, be it fixed, variable, or programmable. They provide not only a stock of off-the-shelf models, but can also design and manufacture custom models for meeting specialty decibel values, form factor, power handling, or other unique parameters.

One important thing to keep in mind is that specified values for attenuation are only guaranteed at 50+j0 ohms, or whatever the characteristic impedance of the attenuator model happens to be (50 and 75 ohms most common). The farther away from the characteristic impedance the connected ports are, the farther from the spec the attenuation value will be.

I provide an online attenuator calculator here.

Please consider contacting RF Cafe advertisers first for your needs.
