- Contribute to the realization of high-precision GNSS -
Start Production; the NJG1186, FEM for 1.2-GHz-band GNSS.
NISD will start producing the NJG1186, a front-end module (FEM) for high-precision GNSS, including GPS, GLONASS, BeiDou, and Galileo in May.
The NJG1186 includes a pre-SAW filter and a low noise amplifier (LNA) and covers 1.2-GHz band supporting L5/E5/B2/G3/L2C bands (1164 MHz to 1228 MHz). Please refer to Figure 1.
Figure 1. Operating Frequency
In recent years, the number of equipment that requires high-precision location information, such as automobiles, drones, and wearable devices, has been increasing. For high-precision positioning, it is necessary to have multi-band capability to receive signals of 1.2-GHz band in addition to the conventional 1.5-GHz band.
Since GNSS is installed in a variety of equipment, it is expected to be used in a variety of environments. Therefore, there are several requirements for different environments, such as high humidity resistance for outdoor use, and space saving for small equipment.
We will further add FEM products for high-precision GNSS to our products lineup to meet these requirements.
For reference, the NJG1186-A, an AEC-Q100 grade 2 and VDA 6.3 compliant version of this product, will be produced in August.
NJG1186 (HFFP10-JL Package)
Features
1. High Gain and Low Noise Figure (NF) in the 1.2-GHz Band
In the 1.2-GHz band (1164 MHz to 1288 MHz), a high gain of 19.5* dB and a low noise figure (NF) of 1.7* dB are achieved.
* These values include SAW filter losses.
2. Highly Airtight and Reliable Package
The use of a highly airtight package (1.57 × 1.23 × 0.47mm) with a metal lid achieves high reliability. It is suitable for automobile and outdoor applications.
3. Small and Thin Package
It is mounted in a small package of 1.57 × 1.23 × 0.47mm with a SAW filter and an LNA included. This enables reducing mounting area.
4. High-Precision Positioning with NJG1159
Using the NJG1186 with the NJG1159, a 1.5-GHz-band FEM, provides higher precision positioning by configuring a multi-GNSS circuit. Please refer to the example of multi-GNSS application in Figure 2.
