MAX2651 - Low-Noise Amplifiers

Key Features

  • 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 MAX265.

MAX2651/MAX2652/MAX2653 19-1506; Rev 2; 8/03 GSM900 and DCS1800/PCS1900 Dual-Band, Low-Noise Amplifiers General Description Features 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 lowpower shutdown mode.
