SP43204 Datasheet, PDF (1/7 Pages) SIPAT Co,Ltd – 50 Ω RF Digital Attenuator

Product Description
The SP43204 is a 50Ω, HaRP™-enhanced, high linearity, 2-bit
RF Digital Step Attenuator (DSA) covering an 18 dB
attenuation range in 6 dB steps. With a parallel control
interface, it maintains high attenuation accuracy, fast switching
speed, low insertion loss and low power consumption. This
next generation SPIePreAgTriDneSADSisAaivsaailvaabileabinleain3ax33mx3mm1m2-12-
lead QFN footprint.
The SP43204 is manufactured on SIPAT's CMOS
process, a patented variation of silicon-on-insulator (SOI)
technology on a sapphire substrate, offering the performance
of GaAs with the economy and integration of conventional
CMOS.
