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, low-
power, high-frequency analog circuits along with
CMOS control function. The ITM1010 uses tiny 12-
pin 2.5mm x 2.5mm Leadless Plastic Chip Carrier
(LPCC) package, which is the smallest CDMA
receiver chip in the world.
