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.

8. Layout Guidelines
The guidelines listed below help the users to achieve the optimum performance of ITM1010 when drawing their layout. These guidelines are recommended. n Keep RF signal lines as short as possible to minimize unnecessary losses and radiation. n For the best noise performance of LNA, keep the pad-to-pad distance in LNA input line as short as possible. The minimum distance is recommended. Also, use high Q components in LNA input-matching circuit. n The 0 ohm resistor between pin 10(LNA_E) and ground is used as a degeneration inductor of the LNA for 800MHz application. This component should not be eliminated. It can also be replaced with chip inductors to increase IP3 of LNA at the cost of smaller gain and higher noise figure. n At the mixer outputs (pin 5 and pin 6), keep the differential signal lines of the same length to ensure signal balance. Symmetrical PCB layout is recommended. n High value (47nF) chip capacitors in the evaluation board (Fig. 4-1) are used for optimum IP3 performance of ITM1010. Do not replace these capacitors with smaller value capacitors. n For various duplexer and RF SAW filters, sensitivity and IMD performance can be optimized by tuning R5, L4 and R2 in Fig. 4-1. n Parasitic impedances at pins 8 (MIX_E) and 10 (LNA_E) might affect RF performance significantly because these pins are used as degeneration. Short PCB lines are recommended for these two pins. n Generally, high LO power is preferable for high gain/IIP3 and low noise figure of the mixer.
