PE43205 Datasheet, PDF (1/11 Pages) Peregrine Semiconductor – UltraCMOS® RF Digital Attenuator

Product Description
The PE43205 is a 50Ω, HaRP™ technology-enhanced
fast switching 2-bit RF Digital Step Attenuator (DSA)
designed for use in 3G/4G wireless infrastructure and
other high performance RF applications.
This DSA is a pin-compatible upgraded version of the
PE43204 with a wider frequency and power supply range,
and extended operating temperature range.
Covering an 18 dB attenuation range in 6 dB and 12 dB
steps, it maintains high RF performance and low power
consumption from 35 MHz through 6 GHz. PE43205 is
offered in a 12-lead 3x3 mm QFN package. In addition,
no external blocking capacitors are required if 0 VDC is
present on the RF ports.
The PE43205 is manufactured on Peregrine’s
UltraCMOS^® process, a patented variation of silicon-on-
insulator (SOI) technology on a sapphire substrate.
Peregrine’s HaRP™ technology enhancements deliver
high linearity and excellent harmonics performance. It is
an innovative feature of the UltraCMOS process, offering
the performance of GaAs with the economy and
integration of conventional CMOS.
