The PE43702 is a HaRPTM-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 50 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. Performance does not change with Vdd due to on-board regulator. This next generation Peregrine DSA is available in a 4x4 mm 24 lead QFN footprint.
