ATTENUATORS
Pasternack's Attenuators are used in a wide variety of applications to satisfy requirements where a reduction in power is needed. Attenuators are often used to extend the dynamic range, reduce signal levels and match circuits. They are available with number of connector options including 2.9mm, 7/16, 7mm, BNC, Type F, Type N, SMA, and TNC.
For bench mount testing applications, also see our lines of Continuously Variable, Rotary, Programmable, Push-Button, and Toggle Attenuators.

Broadband Digital Step Attenuators - 75 Ohm
Peregrine's highly linear, monolithic RF DSA family offers a selection of resolutions, minimum attenuation step sizes and termination impedances. Its UltraCMOS™ foundation allows for a unique initial attenuation state at power-up and a standard programming sequence and footprint across the 5 and 6 bit family. The DSA line provides industry-leading linearity over frequency and temperature, a versatile parallel or serial CMOS control interface, and operates on a single 3-volt supply, making it ideal for applications such as wireless base station, fixed wireless, microwave, VSAT, broadband telecom, military, space, test instrumentation, and optical equipment.

The Arcoptix electrical adjustable variable attenuator is a worldwide unique liquid crystal device that permits to control precisely the attenuation of a free space traveling beam with a simple applied voltage. The variable gray filter functions for polychromatic or monochromatic light as well as for unpolarized or polarized white light. It does not significantly alter the spectrum of the incident light and functions almost equally for wavelengths between 350nm and 700nm. The Arcoptix variable attenuator can so be considered as an ideal variable gay filter in the visible. Notice that this is not the case for usual liquid crystal attenuators that are designed to attenuate efficiently only a single wavelength! Also in the off state the Arcoptix attenuator shows a higher transmission (for unpolarized light) than usual attenuators and it does not alter significantely the polarization state of the light (polarization maintaining element).
