MAX2651, MAX2652, MAX2653 GSM900 And DCS1800/PCS1900 Dual-Band, Low-Noise Amplifiers

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 optimized 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 functionally 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) performance at the GSM, DCS, and PCS bands. A pull-up resistor to VCC 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 MAX, while the MAX2653 is packaged in an 8-pin MAX. All devices operate from 883 a single +2.7V to +3.3V supply.
