With a parallel control interface, it maintains high attenuation accuracy, fast switching speed, low insertion loss and low power consumption. This Peregrine DSA is available in a 3x3 mm 12-lead QFN footprint. The PE43620 is manufactured on Peregrine’s Ultra CMOS process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of Ga As with the economy and integration of conventional CMOS. ©2018, p Semi Corporation.

DOC-88158-3 - (06/2019) PE43620 50 Ω RF Digital Attenuator Absolute Maximum Ratings Exceeding absolute maximum ratings listed in Table 1 may cause permanent damage. Operation should be restricted to the limits in Table 2. Operation between operating range maximum and absolute maximum for extended periods may reduce reliability. ESD Precautions When handling this Ultra CMOS device, observe the same precautions as with any other ESD-sensitive devices. Although this device contains circuitry to protect it from damage due to ESD, precautions should be taken to avoid exceeding the rating specified in Table 1. Latch-up Immunity Unlike conventional CMOS devices, Ultra CMOS devices are immune to latch-up. Table 1 - Absolute Maximum Ratings for...
