Product Description
This product is a high linearity, 6-bit RF Digital Step Attenuator
(DSA) covering a 31.5 dB attenuation range in 0.5 dB steps.
The Peregrine 50Ω RF DSA provides a parallel CMOS control
interface and it operates on 3-volt to 5-volt supply. It maintains
high attenuation accuracy over frequency and temperature and
exhibits very low insertion loss and low power consumption.
This Peregrine DSA is available in a 4x4 mm 24 lead QFN
footprint with an exposed ground paddle.
The PE4309 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.
