Introduction

AI Translation

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 µMAX, while the MAX2653 is packaged in an 8-pin µMAX. All devices operate from a single +2.7V to +3.3V supply.
