PE43704_14 Datasheet, PDF (1/20 Pages) Peregrine Semiconductor – UltraCMOS® RF Digital Step Attenuator

Product Description
The PE43704 is a HaRP™ technology-enhanced, high
linearity, 7-bit 50Ω RF Digital Step Attenuator (DSA). It
offers maximum power handling of 28 dBm up to 8 GHz
and covers a 31.75 dB attenuation range in 0.25 dB,
0.5 dB, or 1.0 dB steps. The PE43704 is a pin-compatible
version of PE43703. It provides multiple CMOS control
interfaces and an optional Vss_EXT bypass mode to
improve spurious performance. It maintains high
attenuation accuracy over frequency and temperature and
exhibits very low insertion loss and low power
consumption. No blocking capacitors are required if DC
voltage is not present on the RF ports.
The PE43704 is manufactured on Peregrine’s
UltraCMOS^® 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.
