General Description
The MAX2642/MAX2643 low-cost, high third-order inter-
cept point (IP3), low-noise amplifiers (LNAs) are
designed for applications in cellular, ISM, SMR, and
PMR systems. They feature a programmable bias,
allowing the IP3 and supply current to be optimized for
specific applications. These LNAs provide up to 0dBm
input IP3 while maintaining a low noise figure of 1.3dB.
The gain for these devices is typically 17dB. The
MAX2642 also features a 13dB attenuation step, which
extends the LNA’s dynamic range. Both devices feature
a shutdown mode that minimizes power consumption.
On-chip output matching saves board space by reduc-
ing the number of external components.
The MAX2642/MAX2643 are designed on a low-noise,
advanced silicon-germanium (SiGe) process technolo-
gy. They operate from a +2.7V to +5.5V single supply
and are available in the ultra-small 6-pin SC70 package.
