Product Specification
PE42440
Product Description
The PE42440 is a HaRP™-enhanced SP4T RF Switch
developed on the UltraCMOS™ process technology. This
general-purpose switch contains 4 identical RF ports and can
be used in a multitude of applications up to 3000 MHz. It
integrates on-board CMOS control logic with a low voltage
CMOS-compatible control interface and requires no DC
blocking capacitors. This RoHS-compliant part is available in a
standard 3x3x0.75mm QFN package.
Peregrine’s HaRP™ technology enhancements deliver high
linearity and exceptional harmonics performance. It is an
innovative feature of the UltraCMOS™ process, providing
performance superior to GaAs with the economy and
integration of conventional CMOS.
