The MAX2667/MAX2669 are high-gain, low-noise amplifiers (LNAs) designed for GPS L1, Galileo, and GLONASS applications. They achieve high gain and low noise figure, while maximizing the input-referred 1dB compression point and the 3rd-order intercept point. The devices operate from a +1.6V to +3.3V single supply. The MAX2667 is optimized for low current, while the MAX2669 is optimized for high linearity. The shutdown feature reduces the supply current to less than 10μA. The devices are available in a small wafer-level package that is lead-free and RoHS-compliant.
The MAX2667 and MAX2669 are high‑gain, ultra‑low‑noise LNAs designed for GPS L1, Galileo, and GLONASS applications. They operate from a single‑supply voltage of 1.6 V to 3.3 V, with the MAX2667 optimized for low current (4.1 mA) and the MAX2669 for high linearity. Both devices include a shutdown pin that reduces supply current to less than 10 µA and are offered in a tiny 0.86 mm × 1.26 mm × 0.65 mm lead‑free, RoHS‑compliant wafer‑level package (WLP).
Typical applications include automotive navigation, mobile devices, telematics, cellular phones with GPS, notebook PCs, marine navigation, and avionics. The handbook lists key features such as 19 dB high‑power gain (MAX2667), 0.65 dB noise figure, integrated 50 Ω output matching, and a low bill‑of‑materials design. It also provides absolute maximum ratings, DC and AC electrical characteristics, typical operating curves, bump configuration details, and PCB layout recommendations.
