PE4305 Datasheet (Peregrine Semiconductor)

PE4305, RF Digital Attenuator

The PE4305 is a high linearity, 5-bit RF Digital Step Attenuator (DSA) covering a 15.5 dB attenuation range in 0.5 dB steps, and is pin compatible with the PE430x series.

This 50-ohm RF DSA provides both parallel (latched or direct mode) and serial CMOS control interface, operates on a single 3-volt
