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. This 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 and low power consumption. This next generation Peregrine DSA is available in a 4x4 mm 24 lead QFN footprint. Programming Modes: Direct Parallel, Latched Parallel or Serial Mode 框图
