Product Description
The PE4261 SP4T RF UltraCMOS鈩?Flip Chip
Switch is designed specifically to address the
needs of the antenna switch module market
for GSM Handsets. On-chip CMOS decode
logic is used to facilitate two-pin, low voltage
CMOS control inputs. High ESD tolerance of
1500 V at all ports, no blocking capacitor
requirements and on-chip SAW filter over-
voltage protection devices make this the
ultimate in integration and ease of use.
The PE4261 is manufactured on Peregrine鈥檚
UltraCMOS鈩?process, a patented variation of
silicon-on-insulator (SOI) technology on a
sapphire substrate, offering the performance
of GaAs with the economy and integration of
conventional CMOS.
