PE43601_15 Datasheet, PDF (1/13 Pages) Peregrine Semiconductor Corp. – RF Digital Attenuator

Product Description
The PE43601 is a HaRP™-enhanced, high linearity, 6-bit RF
Digital Step Attenuator (DSA). This highly versatile DSA
covers a 15.75 dB attenuation range in 0.25 dB steps. The
Peregrine 50Ω RF DSA provides a serial-addressable CMOS
control interface. It maintains high attenuation accuracy over
frequency and temperature and exhibits very low insertion loss
and low power consumption. Performance does not change
with V_DD due to on-board regulator. This next generation
Peregrine DSA is available in a 5x5 mm 32-lead QFN footprint.
The PE43601 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.
