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

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.
