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.

PE4308 Features

* Attenuation: 1 dB steps to 31 dB

* Flexible parallel and serial programming interfaces

* Latched or direct mode

* Unique power-up state selection

* Positive CMOS control logic

* High attenuation accuracy and linearity over temperature and frequency
