General Description
The MAX2651/MAX2652/MAX2653 silicon germanium
(SiGe), low-noise amplifiers (LNAs) are intended for use
in GSM900, DCS1800, and PCS1900 band wireless
handsets. The MAX2651/MAX2652 consist of two LNAs,
one optimized for the GSM900 band and the other opti-
mized for the DCS1800/PCS1900 bands. They feature a
band-select pin to switch between the two LNAs, as well
as a gain-step input to reduce the gain of each LNA by
20dB and reduce supply current. The MAX2652 is func-
tionally equivalent to the MAX2651, but features a low-
power shutdown mode. The MAX2653 consists of a
single LNA optimized for the DCS1800 and PCS1900
bands, and has a shutdown feature and a 20dB gain
step.
The MAX2652 and MAX2653 together form an ideal
solution for triple-band phone applications (GSM, DCS,
and PCS bands).
The MAX2651/MAX2652/MAX2653 are fabricated using
an advanced high-frequency SiGe bipolar process. As
a result, all devices provide low noise figure, high gain,
and high input third-order intercept point (IP3) perfor-
mance at the GSM, DCS, and PCS bands. A pull-up
resistor to V
CC
at each LNA output allows for gain
adjustability. A minimal number of external components
are needed for input and output matching, helping to
reduce board space.
The MAX2651/MAX2652 are packaged in a 10-pin μMAX,
while the MAX2653 is packaged in an 8-pin μMAX. All
devices operate from a single +2.7V to +3.3V supply.
