ITM1010TR

ITM1010 CDMA Cellular/CDMA450 Receiver RF Front-end IC Description The ITM1010 is an integrated receiver front-end IC for 800 MHz Cellular CDMA and 450MHz CDMA450 mobile phones. The device has an LNA and a down-converter on a single die. Its low noise amplifier and mixer have high linearity and high gain. The LNA has two-step gain control scheme, increasing dynamic range while saving current. Gain, noise figure, and linearity of the mixer can be easily adjusted using an external inductor. The ITM1010 is fabricated on an advanced SiGe BiCMOS process which facilitates low -noise, lowpower, high-frequency analog circuits along with CMOS control function. The ITM1010 uses tiny 12pin 2.5mm x 2.5mm Leadless Plastic Chip Carrier (LPCC) package, which is the smallest CDMA receiver chip in the world.
