PE43072 - Peregrine Semiconductor

PE43072 RF Digital Attenuator

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.
