PE42451_14 Datasheet, PDF (1/11 Pages) Peregrine Semiconductor – SP5T Absorptive UltraCMOS® High-Isolation RF Switch

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.
