Introduction

The MAX2686L/MAX2693L low-noise amplifiers (LNAs) are designed for GPS L1, Galileo, and GLONASS applica­ tions. Designed in Maxim’s advanced SiGe process, the devices achieve high gain and low noise figure while maxi­ mizing the input-referred 1dB compression point and the 3rd-order intercept point. Both devices include an internal LDO ideal for battery-powered applications. For currentsensitive applications, the MAX2693L achieves excellent performance while consuming only 1.8mA current. The devices operate from a +1.6V to +4.2V single sup­ ply. The shutdown feature reduces the supply current to less than 20μA. The devices are available in a very small, lead-free, RoHS-compliant, 0.86mm×0.86mm×0.65mm wafer-level package (WLP).

The MAX2686L/MAX2693L are LNAs designed for GPS L1, Galileo, and GLONASS applications. The devices fea­ ture an optional power-shutdown control mode to elimi­ nate the need for an external supply switch. The devices achieve high gain and low noise figure in an ultra-small package ideal for space-sensitive applications. These integrated ICs eliminate the need for an external LDO.
