PE4302-52.pdf

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

the user to select an initial attenuation state at power-up. The

PE4302 exhibits very low insertion loss and low power

consumption. This functionality is delivered in a 4x4 mm QFN

footprint.

The PE4302 is manufactured on Peregrine’s UltraCMOS™

process, a patented variation of silicon-on-insulator (SOI)

technology on a sapphire substrate, offering the performance

of GaAs with the economy and integration of conventional

CMOS.
