Description

The PE43703 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, 0.5 dB, or 1.0 dB steps. The customer can choose which step size and associated specifications best suit their application. The Peregrine 50 RF DSA provides multiple CMOS control interfaces and an optional external Vss feature. PE43703 maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and low power consumption. This next generation Peregrine DSA PE43703 is available in a 5x5 mm 32-lead QFN footprint.Programming Modes: Direct Parallel, Latched Parallel and Serial-Addressable (Program up to eight addresses 000 - 111)
