ITM2010
Description
The ITM2010 is an optimized LNA/Mixer IC for dual-band tri-mode applications.
It provides a receiver front-end for cellular CDMA/AMPS and PCS functions
on a single chip. The LNAs/Mixers for both bands are designed for high
gain, high linearity, and low noise figure with flexible optimization
of performance. The device offers an easy control of linearity and current,
using one external resistor, as well as a gain control to minimize inter-modulation
and cross-modulation due to strong jammers. The ITM2010 includes an internal
LO frequency divider which allows the use of a single VCO for both Cellular
and PCS bands. In addition the device optionally supports the use of dual
VCOs for old designs. The ITM2010 is fabricated on an advanced SiGe BiCMOS
process, and is available in a small 24-pin 4mm x 4mm Leadless Plastic
Chip Carrier (LPCC) package.
