A0 A1 A2 P/S VDD VSS_EXT Product Description
The PE43614 is a 50Ω, HaRP™ technology-enhanced, 6-bit RF digital step attenuator (DSA) that supports a
wide frequency range from 9 kHz to 45 GHz. The PE43614 features glitch-safe attenuation state transitions,
supports 1.8V control voltage and optional VSS_EXT bypass mode to improve spurious performance, making this
device ideal for test and measurement, point-to-point communication systems, and very small aperture
terminals (VSAT). …
