General Description
The MAX2374 silicon-germanium (SiGe), switchable-
gain, variable-linearity, low-noise amplifier (LNA) is
designed for cellular-band, code-division multiple-
access (CDMA). It can be used for applications such
as TDMA and PDC or wherever high dynamic range
and low noise are required. This LNA provides a high
intermodulation intercept point (IIP3), which is
adjustable to meet specific system requirements by
selecting an appropriate external resistor. To achieve
high gain and low noise, the LNA is packaged in a tiny
ultra-chip-scale package (UCSP) with six solder
bumps. The LNA operates from a +2.7V to +5.5V single
supply and consumes just 8.5mA while achieving a
+6.2dBm input IIP3. Supply current reduces to less
than 1µA in shutdown mode.
The MAX2374 provides two gain modes. High-gain
mode optimizes system sensitivity, while low-gain mode
optimizes system linearity.
