END OF LIFE
The pin-compatible drop-in replacement for the PE43503 is the PE43711. Please contact your local sales representative with any questions.
The PE43503 is a HaRP™ technology-enhanced, high linearity, 5-bit RF Digital Step Attenuator (DSA) covering a 31 dB attenuation range in 1 dB steps. The Peregrine 50Ω RF DSA provides a serial 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.
