GNSS LNAs

Tracking precision and signal quality for single- and dual-band applications

anchor

Overview

Devices using GNSS such as personal navigation devices (PND), tablets, smart watches, and mobile phones require a low or ultra-low noise amplifier (LNA) as well as high linearity to enhance receiver sensitivity for best localization even under bad conditions or low-battery.

Key Features

  • Dual-band with one GNSS LNA
  • L1 + L2/L5 simultaneously
  • Up to 21 dB gain
  • Up to 1.1 mA
  • Up to 0.5 NF

About

Low-power or high-linearity GPS LNAs

Infineon’s range of ultra-low power LNAs preserves valuable battery power at a high gain. They are ideal for those applications where battery life is the primary focus. When power consumption is not an issue, Infineon’s high-linearity LNAs can offer solid performance and ultra-low noise figures.

Benefits of dual-band GPS LNAs

GPS LNAs used in dual-band configurations offer many advantages over single-band solutions:

  • Interference rejection: By covering two frequency bands (L1+L2/L5), LNAs can mitigate interference from nearby signals or other sources, improving the system’s resilience and resulting in more accurate signal reception.
  • SNR improvement: Both the strength of the signal and its simultaneous amplification result in better signal quality and improved GPS positioning.
  • Futureproofing: Dual band provides compatibility in current and future GPS systems that may utilize two or more frequency bands. 

Infineon covers dual band in two ways: 

  • A single LNA covering two bands simultaneously (L1+L2/L5 using a single LNA) 
  • Classic two single-band LNAs approach (using two LNAs both covering L1 and L2/L5 bands)

Infineon offers a wide range of GPS (GNSS) LNAs products with high compatibility and flexible design.

GNSS LNA designs

Infineon’s range GPS LNAs allow developers of smartphones, tablets, cameras, and wearables to integrate smaller but more powerful navigation systems into their designs. Improving signal sensitivity enables users to have better access to precise navigation systems in both urban and remote environments.
