By far the most power efficient GNSS sensor for your business products!



GNSS system-on-chip (SoC) sensor

QLX300 Video Introduction

Product Description

The Qualinx QLX300 chip is an ultra-low power, fully-integrated multi-constellation GNSS solution. The QLX300 supports concurrent reception of GPS/QZSS/SBAS, Galileo, GLONASS, and Beidou navigation satellite signals. This high-end product delivers the most power efficient GNSS solution available with a high sensitivity. It enables customers to lengthen battery life in their products while offering the lowest BOM cost. The QLX300 can operate at supply voltage of 1–3.6V, offers running from a Zinc-air or single-cell battery.

The QLX300 Baseband Engine has 100+ fully reconfigurable baseband channels in a GlobalFoundries FDX process to deliver a high sensitivity and fast time-to-first fix (TTFF).


Ultra-Low Power Consumption

The QLX300 RF front-end leverages Qualinx Digital/Discrete-Time RF (DRF) technology to reduce the power consumption. Its navigation baseband engine utilized an innovative architecture to present superior performance while consuming extremely low-power. The QLX300 offers superior performance with 10X less power consumption than available products. The QLX300 also features an excellent off-leakage current of 100nA.

Lowest BOM Cost

The QLX300 includes built-in LNA, LDO, PMU, GPIO (SPI/I2C/UART), and ARM (Cortex M0) processor. The LNA matching network is also integrated and it does not need any external component. The QLX300 supports TCXO as well as low quality crystal oscillators to further reduce system cost. Being able to operate from a single cell battery, the QLX300 provides additional flexibility to further reduce system cost.

Smallest Form Factor

The product will be delivered in industry standard wafer-level chip scale package (WLCSP24) measuring just 2 x 2 x 0.5 mm. It would be the smallest form factor available GNSS solution.


The QLX300 is an ideal stand-alone GNSS solution for wearables and asset/fleet/livestock tracking, where small size, ultra-low power, and low-cost are mandatory. Combining these features with its high performance makes the QLX300 a perfect choice for below applications.
