Product Specification
PE42851
Product Description
The PE42851 is a HaRP™ technology-enhanced SP5T
high power RF switch supporting wireless applications
up to 1 GHz. It offers maximum power handling of
42.5 dBm continuous wave (CW). It delivers high
linearity and excellent harmonics performance. It has
both a standard and attenuated RX mode. No blocking
capacitors are required if DC voltage is not present on
the RF ports.
The PE42851 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.
