SiGe: C Low Noise Amplifiers (LNAs)

The BGU700x and BGU8007 series of low noise amplifiers from NXP Semiconductors offer the smallest footprint in the market. They use adaptive biasing to immediately detect any output power from jammers, and compensate by temporarily increasing the current, resulting in signal reception maintenance for longer periods of time.

The BGU7000x series is the industry's first GPS LNAs with the ability to suppress cellular, Bluetooth, and WLAN transmit signals. This series of LNAs also improves weak reception on GPS signals by 10 dB or better IP3 under -40 to -20 dBm jamming conditions, while the noise figure remains below 1 dB. In addition to those features, this series save up to 50 percent in PCB size, 10 percent in component cost, and require only two external components.

The BGU8007 series of low noise amplifiers is optimal for GNSS receiver applications, and has the ability to adapt itself to a changing environment through co-habitation of different radio systems in modern cellular handsets. If jamming signals from co-existing cellular transmitters are present, this LNA has been designed for low power consumption coupled with high performance.

Key Features for the Series:

• Low noise figure: 0.75 dB
• System-optimized gain of 16.5 or 19 dB
• AEC-Q100 qualified (BGU7004, BGU7008) for highest reliability in harsh conditions
• Small 6-pin leadless package: 1.45 x 1.0 x 0.5 mm
