PCTEL, Inc. RF Antennas C-3961D

The C-3961D is a low noise GPS embedded antenna designed for optimal performance in embedded applications. It features a tuned custom ceramic patch element that minimizes detuning effects from nearby objects, ensuring a consistent and clear signal. The antenna has a low noise figure of 0.5 dB, making it suitable for environments with challenging GPS conditions. It includes a 45.2 mm diameter mini ground plane and offers 15 kV ESD circuit protection. The antenna operates within a frequency range of 1575.42 ± 10 MHz and provides a gain of 28 dB at 3.3 VDC and 30 dB at 5 VDC. The polarization is right-hand circular, and it has a maximum VSWR of 1.5:1 with a nominal impedance of 50 ohms. The C-3961D has a compact size of 1.85 inches in diameter and 0.32 inches in height, weighing 0.56 ounces. It operates within a temperature range of -40°C to +85°C and can withstand humidity levels up to 95% (non-condensing). This antenna is RoHS compliant, making it suitable for environmentally conscious projects.
