PE43703 7-bit Digital Step Attenuator

pSemi's 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 are best suited for their application. The pSemi 50 Ω RF DSA provides multiple CMOS control interfaces and an optional external V_SS feature. It maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and low power consumption. Performance does not change with V_DD due to on-board regulator. This next generation pSemi DSA is available in a 5 mm x 5 mm 32-lead QFN footprint.
