Product Description
The PE4268 SP6T RF UltraCMOS™ Switch addresses the
specific design needs of the Quad-Band GSM Handset
Antenna Switch Module Market. Broadband performance also
makes it a versatile solution in other IF and RF applications.
The switch includes two high power paths with low insertion
loss and four low power paths with high isolation. On-chip
CMOS decode logic facilitates three-pin low voltage CMOS
control. High ESD tolerance of 1500 V at all ports and no
blocking capacitor requirements make this the ultimate in
integration and ruggedness.
The PE4268 UltraCMOS™ RF Switch is manufactured in
Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS
process, offering the performance of GaAs with the economy
and integration of conventional CMOS.
