MAX2651EUB-MAX2652EUB-MAX2653EUA
GSM900 and DCS1800/PCS1900 Dual-Band / Low-Noise Amplifiers
General DescriptionThe 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 VCCat 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.

otherwise noted. Typical values are at VCC= +3V, TA= +25°C.) (Note 1)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
