SP42450 Datasheet, PDF (1/10 Pages) SIPAT Co,Ltd – SP5T Absorptive Silicon-on-Sapphire

Product Description
The SP42450 is a linearity enhanced Absorptive SP5T RF Switch
developed on the Silicon-on-Sapphire (SOS) 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.
The design methodology, used to create the SP5T RF Switch, is a
technology that enhances linearity and has exceptional harmonics
performance. It is an innovative feature of the Silicon-on-Sapphire
process, providing performance superior to GaAs with the economy
and integration of conventional CMOS.
