NXP Semiconductors RF Amplifiers BGU8309Z

The BGU8309 is a low-noise amplifier (LNA) designed for GNSS receiver applications, including GPS, GLONASS, Galileo, and COMPASS. It operates within the full GNSS L1 band, covering frequencies from 1559 MHz to 1610 MHz. The amplifier is housed in a compact 5-pin leadless package measuring 0.8 mm x 0.8 mm x 0.35 mm, making it suitable for space-constrained applications. This device features a low supply current of 3.6 mA while providing a gain of 17 dB and a noise figure of 0.65 dB at low jamming power levels. It is optimized for performance in environments with co-existing cellular transmitters, temporarily increasing its bias current during high jamming conditions to enhance sensitivity. The BGU8309 has an input 1 dB compression point of -9 dBm and an out-of-band input third-order intercept point of 5 dBm. The amplifier requires only one external matching inductor and includes integrated supply decoupling and temperature-stabilized biasing for ease of design. It also features ESD protection on all pins and operates with a supply voltage range of 1.5 V to 3.1 V. The power-down mode current consumption is less than 1 µA, making it energy-efficient for battery-operated devices. Applications include smartphones, tablets, digital cameras, and wearable devices.
