JTT2450S25P4X

Antennas RF Overview

The JTT2450S25P4X is a right-hand circularly polarized (RHCP) patch antenna manufactured by JC Antenna, designed for operation at the 2.45 GHz ISM band. It features a center frequency of 2450 ± 5.0 MHz with a typical gain of 3.5 dBi at zenith and an axial ratio of ≤5.0 dB at the center frequency. The component requires a ground plane measuring 27 x 27 mm and exhibits a return loss of ≥15 dB and VSWR performance at the operating frequency. Its bandwidth exceeds 60 MHz based on 10 dB return loss criteria, with a frequency temperature coefficient of ±20 ppm/℃.

Antennas RF Feature Summary

• Right-hand circular polarization (RHCP) design for signal integrity
• Patch antenna construction optimized for 2.45 GHz operations
• Stable performance across temperature variations with defined frequency coefficient

Antennas RF Applications

• GNSS receiver modules requiring RHCP input
• Wireless sensor networks operating in the 2.4 GHz band
• IoT devices utilizing Bluetooth or Zigbee protocols

Antennas RF Procurement Notes

Verify that the specific batch matches the manufacturer's current production specifications. Confirm the physical dimensions align with the required 27 x 27 mm ground plane constraint during integration. Ensure the procurement source provides valid documentation confirming the component's origin from Zhejiang JC Antenna Co., Ltd. to guarantee authenticity and compliance with technical standards.

Antennas RF Selection Notes

Select this component when Right-Hand Circular Polarization is mandatory for the application environment. The 2.45 GHz center frequency suits ISM band applications rather than standard cellular bands. Engineers must account for the specified 27 x 27 mm ground plane requirement in the PCB layout to maintain the stated 3.5 dBi gain and axial ratio performance metrics.
