About

High signal reception and immunity to interference

GNSS are among the most important aspects of personal navigation devices, smartphones, wearable devices, robots, and vehicles. Many of these devices are integral to the ongoing enablement of the IoT. In order to provide precise location coordinates and global coverage, and thereby power the increased usability of many IoT functions, GNSSs must exemplify a high signal reception sensitivity as well as immunity to interference. 

Diving into specifics, since GNSS satellite signals are transmitted at an extremely low power level of about -130 dBm, high-power jammer signals may leak into the GNSS receiver and impact the receiver’s sensitivity by overdriving the LNA. This interference presents a major challenge to RF FE designers working to maintain the receiver’s sensitivity to the relatively weak and low-power incoming GNSS signals. You can overcome this challenge and more with Infineon's diverse GNSS product portfolio, which enables you to achieve excellent system sensitivity, low power consumption, and quick time to first fix.

Infineon's enabling low-noise amplifier portfolio for GNSS

Infineon's product portfolio of semiconductor solutions for GNSS applications is led by our robust low-noise amplifiers (LNAs) that are available in two broad categories: 

  • Our ultra-low-power LNAs preserve valuable battery power at a high gain. They're ideal for applications where battery life is the primary focus, benefitting from the combination of high gain and excellent noise figure. 
  • On the other hand, when power consumption is not an issue, Infineon’s high-linearity LNAs combine the robustness against out of band interference signals with ultra-low noise figure.

We also offer LNAs that can be used in dual-band configurations, providing benefits over single-band configurations such as interference rejection, SNR improvement, and future-proofing. We accomplish this with either a single LNA covering two bands simultaneously (L1+L2/L5 using a single LNA) or a classic two single-band LNAs approach (using two LNAs both covering L1 and L2/L5 bands).

By selecting Infineon, you can achieve top navigation precision and the best reception, using compact products in the standard industry footprint.

Ultra-low-power GNSS LNAs for wearables and mobile cellular IoT

Ultra-low-power GNSS LNA for wearables and mobile cellular IoT applications.

These LNAs are designed to enhance the GNSS signal sensitivity for the L2/L5 band, especially when used in wearables and mobile cellular IoT applications. These high-performance LNAs ensure high system sensitivity and preserve valuable battery power with their ultra-low power consumption of 1.5 mW, which is ideal for GNSS in small battery-powered devices such as smartwatches and smartphones, often integral in the IoT.

Test it out for yourself and reduce your time to market with our LNA evaluation boards.
