Electromagnetic Interference (EMI) is emerging as a major concern in next generation wireless communication systems. As wireless terminals now support multiple services and features that utilize high data rates simultaneously, removing interference within wireless terminals like handsets has become a challenge.

Features

• Protocol agnostic. Designed for: GSM, CDMA, DVB-H, ISDB-T, DMB

• Frequency Range 300MHz to 3GHz

• Integrated, programmable LNA gain stages in the sampler path

• SPI bus controlled integrated DACs

• >20dB Noise Cancellation is possible

• 50dB typical Dynamic Range

• Low Power Consumption (<20mW typical, ~2µW standby)

• Ultra Small ~ 1mm2 devices are available as tested bumped die or 3x3mm2 QFN package

Applications

• Most any wireless device with a local aggressor:

- Cell phones

- Mobile TV devices

- Laptop Computers

- GPS terminals

- Pico- and Femtocells

• Improved Tx to Rx Isolation of devices (i.e. duplexer, switches) or between neighboring antennae

• Basestations

• Linearization of PAs
