If customers adopt SMA connector, big RF solder pad might result in great parasitic capacitance, which will affect the antenna performance. Remove the copper on the first and second layers under the RF solder pad. Figure 4-4 Recommended RF PCB design Copyright © Neoway Technology Co., Ltd... -
Page 22: Reference Design Of Active Gnss Antenna
The power supply of the active antenna is fed by the 47 to 100 nH inductor through the signal traces. Keep GNSS antenna circuit far away from the communications antenna circuits on PCB. Otherwise, these two parts will jam each other, lowing the RF performance. Copyright © Neoway Technology Co., Ltd... -

Neoway will not provide warranty for heat-responsive element abnormalities caused by improper temperature control. For information about cautions in G6 storage and mounting, refer to Neoway Module Reflow Manufacturing Recommendations. When manually desoldering G6, use heat guns with great opening, adjust the temperature to 250 degrees (depending on the type of the solder paste), and heat the module till the solder paste is melt. -
