Product Specification
PE42451
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.
