The PE43501 is a HaRP-enhanced, high linearity, 5-bit RF Digital Step Attenuator (DSA). This highly versatile DSA covers a 7.75 dB attenuation range in 0.25 dB steps. The Peregrine 50Ω RF DSA provides a serial-addressable 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 5x5 mm 32-lead QFN footprint.
Programming Modes : Direct Parallel, Latched Parallel and Serial-Addressable (Program up to eight addresses 000 - 111).
