ITM1010
CDMA Cellular/CDMA450 Receiver RF Front-end IC
Description
Features
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.
World’ s smallest 2.5 mm x 2.5 mm CDMA
receiver chip
Operating frequency:
CDMACellular : 869 ~ 894 MHz
CDMA 450 : 460 ~ 470 MHz
High linearity and high gain
Two step LNA gain control
16 dB Gain, 1.2 dB NF, 9.5 dBm IIP3 LNA
Adjustable Gain, NF, IIP3 of mixer 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.
All pins are ESD-protected

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.
