max2659 gpsgnss low noise amplifier

The MAX2659 low-noise amplifier (LNA) is designed for GPS, Galileo, and GLONASS applications. Manufactured using Maxim's advanced SiGe process, the device achieves a gain of 20.5 dB and an ultra-low noise figure of 0.8 dB, while maximizing the input-referred 1 dB compression point and the 3rd-order intercept point at -12 dBm and -5 dBm, respectively. The MAX2659 operates from a +1.6V to +3.3V single supply and consumes only 4.1 mA. The shutdown feature in the device reduces the supply current to less than 1 µA. The MAX2659 is available in a very small, lead-free, RoHS compliant, 1.5 mm x 1.0 mm x 0.75 mm, 6-pin µDFN package.

The MAX2659 low-noise amplifier (LNA) is specifically engineered for high-performance applications in GPS, Galileo, and GLONASS systems. Utilizing Maxim Integrated's advanced silicon-germanium (SiGe) technology, the device is capable of delivering a substantial voltage gain of 20.5 dB while maintaining an exceptionally low noise figure of 0.8 dB. This performance is critical for enhancing signal integrity in sensitive RF environments.

The amplifier's design optimizes the input-referred 1 dB compression point at -12 dBm and the 3rd-order intercept point at -5 dBm, ensuring that the MAX2659 can handle a range of input signal levels without significant distortion. This characteristic is particularly beneficial in scenarios where high linearity is required, such as in multi-tone signals or in the presence of strong adjacent channels.

Power supply requirements for the MAX2659 are flexible, with operation supported over a voltage range of +1.6V to +3.3V. The device exhibits low power consumption, drawing only 4.1 mA during operation, which is advantageous for battery-powered applications. Additionally, the integrated shutdown feature allows the amplifier to reduce its supply current to less than 1 µA when not in use, further enhancing its efficiency and extending battery life.

The MAX2659 is packaged in a compact, lead-free, RoHS compliant 6-pin µDFN configuration, measuring 1.5 mm x 1.0 mm x 0.75 mm. This small footprint is ideal for integration into space-constrained designs, such as portable GPS modules or other RF applications where size and performance are critical. The combination of high gain, low noise, and efficient power management makes the MAX2659 an excellent choice for modern navigation systems.MAX2659 low-noise amplifier (LNA) is designed for GPS, Galileo, and GLONASS applications.
