PE43503 Datasheet (Peregrine Semiconductor)

PE43503, RF Digital Attenuator

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 50Ω RF DSA provides a serial CMOS control interface.

It maintains high attenuation accuracy over frequency and temperature and exhibits very low ins
