The PE43503 is a HaRP"-enhanced, high linearity, 5-bit RF
Digital Step Attenuator (DSA) covering a 31 dB attenuation
range in 1 dB steps. The Peregrine 50& RF DSA provides a
serial 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 Vdd due to on-board regulator. This next
generation Peregrine DSA is available in a 4x4 mm 24-lead
QFN footprint.
The PE43503 is manufactured on Peregrines 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.
