MAX2686L/MAX2693L

GPS/GNSS Low-Noise Amplifiers

with Integrated LDO

General Description

Beneﬁts and Features

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 current-

sensitive applications, the MAX2693L achieves excellent

performance while consuming only 1.8mA current.

● High Power Gain: 19dB (MAX2686L)

● Low Noise Figure: 0.88dB (MAX2686L)

● Integrated 50Ω Output Matching Circuit

● Low Supply Current: 1.8mA (MAX2693L)

● Wide Supply Voltage Range: 1.6V to 4.2V

● Low Bill of Materials: One Inductor, Two Capacitors

● Small Footprint: 0.86mm x 0.86mm

● 0.4mm Pitch WLP

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 x 0.86mm x 0.65mm

wafer-level package (WLP).
