PE42423 Datasheet, PDF (1/11 Pages) Peregrine Semiconductor – UltraCMOS SPDT RF Switch 100 MHz - 6 GHz

Product Description
The PE42423 is a HaRP™ technology-enhanced
absorptive 50Ω SPDT RF switch designed for use in high
power and high performance WLAN 802.11 a/b/g/n/ac
applications such as carrier and enterprise Wi-Fi Products,
supporting bandwidths up to 6 GHz.
This switch features high linearity which remains invariant
across the full supply range. PE42423 also features
exceptional isolation, high power handling and is offered in
a 16-lead 3x3 mm QFN package. In addition, no external
blocking capacitors are required if 0V DC is present on the
RF ports.
The PE42423 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.
