The PE43204 is a 50

Ω, HaRP™-enhanced, high linearity, 2-bit

RF Digital Step Attenuator (DSA) covering an 18 dB

attenuation range in 6 dB steps. With a parallel control

interface, it maintains high attenuation accuracy, fast switching

speed, low insertion loss and low power consumption. This

next generation Peregrine DSA is available in a 3x3 mm 12-

lead QFN footprint.

The PE43204 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.
