50 Ohm Digital Step Attenuators
Peregrine's highly linear, monolithic 50 Ohm RF DSA family offers a selection of resolutions, minimum attenuation step sizes and termination impedances. Its UltraCMOS® foundation allows for an initial attenuation state at power-up. The DSA line provides excellent linearity over frequency and temperature, a versatile parallel or serial CMOS control interface, and operates on a single 3-volt supply, making it capable of addressing the needs of applications such as wireless base station, fixed wireless, microwave, VSAT, broadband telecom, military, space, test instrumentation, and optical equipment.
