PE4308 Datasheet (Peregrine Semiconductor)

PE4308, RF Digital Attenuator

The PE4308 is a high linearity, 5-bit RF Digital Step Attenuator (DSA) covering 31 dB attenuation range in 1dB steps, and is pin compatible with the PE430x series.

This 75-ohm RF DSA provides both parallel (latched or direct mode) and serial CMOS control interface, operates on a single 3-volt supply
