The PE43602 is a HaRP

™-enhanced, high linearity, 6-bit RF

Digital Step Attenuator (DSA) covering a 31.5 dB attenuation

range in 0.5 dB steps. This Peregrine 50

Ω RF DSA provides

both a serial and parallel CMOS control interface. It maintains

high attenuation accuracy over frequency and temperature and

exhibits very low insertion loss and low power consumption.

regulator. This next generation Peregrine DSA is available in a

4x4 mm 24 lead QFN footprint.

The PE43602 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.
