ML81221GD, a CMOS switch with high-isolation that is developed on SOS (silicon-on-sapphire) technology based on Peregrine Semiconductor Corp's UltraCMOS™ process technology.

The ML81221GD is compatible with digital terrestrial TVs including those of one-segment digital TV type for mobile phones and achieves a high level of isolation, 40dB at 900MHz (signal leakage 0.01%), in addition to low power consumption.

The chip also operates with one-fifth lower power consumption than RF switches with GaAS compound semiconductors and withstands over 2,000V of ESD pressure in HBM. Customers can handle the chip the same way as a CMOS LSI in their manufacturing line.
