PE42451 Datasheet, PDF (1/11 Pages) Peregrine Semiconductor Corp. – SP5T Absorptive UltraCMOS

Product Description
The PE42451 is a HaRP™-enhanced Absorptive SP5T RF
Switch developed on the UltraCMOS™ process technology.
This general purpose switch is comprised of five symmetric RF
ports and has very high isolation. An on-chip CMOS decode
logic facilitates a three-pin low voltage CMOS control interface
and an optional external Vss feature (Vss_EXT). High ESD
tolerance and no blocking capacitor requirements make this the
ultimate in integration and ruggedness.
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.
