PE4302 - Peregrine Semiconductor

PE4302 RF Digital Attenuator

The PE4302 is a high linearity, 6-bit RF Digital Step Attenuator “DSA” covering a 31.5 dB attenuation range in 0.5 dB steps. This 50-ohm RF DSA provides both parallel and serial CMOS control interface operates on a single 3-volt supply and maintains high attenuation accuracy over frequency and temperature. It also has a unique control interface that allows t.
