This product can be applied to various applications such as vehicle antennas and GNSS modules.
Features
■ High gain and low NF characteristics are realized in each frequency band of GNSS
The corresponding frequency can be adjusted by replacing the external integrated circuit, achieving a high gain of more than 30dB and a low NF characteristic of 0.6dB in each frequency band from 1.1 to 1.5GHz. This product is used in Multi-GNSS that requires high-precision positioning, and contributes to improving the receiving sensitivity of the GNSS receiver and shortening the positioning time.
■ Improve the freedom of circuit design
The integration of the primary and secondary LNAs is done outside the package, so a filter can be placed between the two LNAs (Figure 2). Compared with the configuration of filters in the front stage of NJG1187, it can more effectively reduce the impact on NF.
Combined with the required characteristics, the circuit configuration can be changed flexibly.
application
Receive GNSS (including GPS, GLONASS, BeiDou, Galileo, etc.) signal use
