Product Description
The PE43702 is a HaRP™-enhanced, high linearity, 7-bit RF
Digital Step Attenuator (DSA). This highly versatile DSA
covers a 31.75 dB attenuation range in 0.25 dB steps. The
Peregrine 50Ω 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. Performance does not
change with V
generation Peregrine DSA is available in a 4x4 mm 24 lead
QFN footprint.
The PE43702 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.
