PE43502 - Peregrine Semiconductor

PE43502 RF Digital Attenuator

The PE43502 is a HaRP™-enhanced, high linearity, 5-bit RF Digital Step Attenuator (DSA). This highly versatile DSA covers a 15.5 dB attenuation range in 0.5 dB steps. The Peregrine 50Ω RF DSA provides multiple CMOS control interfaces. It maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and low power cons.
