BGU Series GPS LNAs

The best reception of GNSS signals with the smallest footprint from NXP

NXP's BGU Series GPS LNAs By dynamically suppressing strong cellular and WLAN transmit signals, an industry first, NXP Semiconductors' LNAs offer the best reception of weak GPS signals. Linearity improves with a 10 dB better IP3 under -40 to -20 dBm jamming conditions, while NF remains below 1 dB. Requiring only two external components, they save up to 50% in PCB size and 10% in component cost, offering the smallest footprint in the market.

These SiGe:C low noise amplifiers (LNAs) improve the reception of GPS signals, including GloNass and Galileo. Available in extremely small 6-pin packages, they reduce footprint, lower cost, and enhance reception in systems that use an active or patch antenna. GPS has become a standard feature in a very wide range of consumer products, from personal navigation devices to digital video cameras, watches, electric cars, and more. GPS signal power levels are weak and below the noise floor at -155 dBm. In many of these products, especially smart phones, strong transmitters such as WLAN and cellular can drive the GPS LNA into compression. When the GPS LNA is in compression, it has lower gain which causes worse GPS reception. And when in compression, the LNA generates intermodulation products and harmonics from the transmitter signals, which can overpower the weak GPS signals and lead to no GPS reception.

Features

  • Low noise figure: 0.75 dB
  • System-optimized gain of 16.5 or 19 dB
  • Adaptive biasing dynamically suppresses strong cellular and WLAN transmit signals, resulting in improved linearity of 10 dB better IP3 under -40 to -20 dBm jamming conditions and effective GPS output with jammer powers up to -15 dBm
  • AEC-Q100 qualified (BGU7004, BGU7008) for highest reliability in harsh conditions
  • Only two external components required
  • Small 6-pin leadless package: 1.45 x 1.0 x 0.5 mm
