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 (VssEXT). 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.
