MAX2686/MAX2688

GPS/GNSS Low-Noise Amplifiers

General Description

Features

The MAX2686/MAX2688 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 ultra-low-noise figure while

maximizing the input-referred 1dB compression point and

the 3rd-order intercept point. The MAX2686 provides a

high gain of 19dB. The MAX2688 supplies 15dB of gain

while attaining higher linearity.

● High-Power Gain: 19dB (MAX2686)

● Ultra-Low-Noise Figure: 0.75dB (MAX2686)

● Integrated 50Ω Output Matching Circuit

● Low Supply Current: 4.1mA

● Wide Supply Voltage Range: 1.6V to 3.3V

● Low Bill of Materials: One Inductor, Two Capacitors

● Small Footprint: 0.86mm x 0.86mm

● Thin Profile: 0.65mm

The devices operate from a +1.6V to +3.3V single supply.

The optional shutdown feature in the devices reduces the

supply current to less than 10µA. The devices are avail-

able in a very small, lead-free, RoHS-compliant, 0.86mm

x 0.86mm x 0.65mm wafer-level package (WLP).
