The TQC-GPS-001 has a VSWR of 1.5:1, ensuring minimal signal loss and optimum performance. Its 50 ohm impedance further enhances signal quality, making it ideal for demanding applications requiring reliable GPS tracking. TQC-GPS-001 adopts right-handed circular polarization (RHCP) antenna, which enhances its ability to receive GPS signals and provides better anti-interference ability. This means you can rely on this GPS receiver to provide consistent and accurate tracking data. In addition, the TQC-GPS-001 has an LNA/filter with a gain of 28dB (without cable) and a noise figure of only 1.5dB. This ensures that the GPS receiver can amplify weak signals and reduce noise, improving signal quality and reliability. In addition, the TQC-GPS-001's built-in filter provides excellent out-of-band attenuation. The minimum attenuation of f0+/-20MHZ frequency band is 7dB, the minimum attenuation of f0+/-50MHZ frequency band is 20dB, and the minimum attenuation of f0+/-100MHZ frequency band is 30dB, which can effectively filter out unwanted frequencies and reduce interference, so as to achieve more accurate and reliable GPS tracking. The TQC-GPS-001 operates from a voltage range of 3V to 5V, providing flexible power supply options. It also features a low DC current draw of 5mA, with a maximum of 10mA, ensuring efficient power usage.
