Datasheet nanoSplatch nSP250 Embedded WiFi/WLAN Antenna The nanoSplatch nSP250 is a surface-mount antenna for embedded WiFi/WLAN and other 2.4 GHz or 5.8 GHz ISM or U-NII frequency band applications. It uses a grounded-line technique to achieve outstanding performance in a tiny surface-mount package. The nSP250 exhibits low proximity effect with a very hemispherical radiation pattern, making it ideal for handheld devices and applications typically subject to interference. The nSP250 is available in tape and reel packaging and is designed for reflow-solder mounting directly to a printed circuit board for high-volume applications. Features Applications Ultra-compact package (9.6 mm x 8.4 mm x Single- and dual-band WiFi/WLAN/802.11 1.1 mm) Bluetooth and ZigBee Excellent performance with smallest ground Smart Home networking plane (40 mm x 20 mm) Sensing and remote monitoring Resistant to proximity effect Hand-held devices Omnidirectional radiation pattern Internet of Things (IoT) devices Direct surface-mount PCB attachment U-NII and ISM applications Reflow- or hand-solder assembly High gain (2.7 dBi at 2.4 GHz, 3.7 dBi at 5.8 GHz) High efficiency (66% at 2.4 GHz, 69% at 5.8 GHz) Ordering Information Part Number Description ANT-DB1-nSP250-B Bulk quantities supplied in cut tape ANT-DB1-nSP250-T Tape and reel (1000 per reel) AEK-DB1-nSP250 Antenna evaluation kit Available from Linx Technologies and select distributors and representatives.nanoSplatch nSP250 Datasheet Electrical Specifications 2.4 GHz ISM U-NII 5.8 GHz ISM/ U-NII-3 Frequency Range 2.4 GHz to 2.5 GHz 5.150 GHz to 5.725 GHz 5.725 GHz to 5.875 GHz VSWR 2.0 : 1 2.2 : 1 2.4 : 1 Peak Gain 2.7 dBi 4.3 dBi 3.7 dBi Average Gain -1.8 dBi -1.9 dBi -1.6 dBi Efficiency 65% 60% 70% Polarization Linear Radiation Omnidirectional Max Power 5 W Wavelength 1/4-wave Impedance 50 Connection Surface-mount Weight 0.16 g (0.006 oz) Dimensions 9.6 mm x 8.4 mm x 1.1 mm (0.38 in x 0.33 in x 0.04 in) Operating Temperature -40 C to +130 C ESD Sensitivity NOT ESD sensitive. As a best practice, Linx may use ESD packaging. Electrical specifications and plots measured with a 40 mm x 20 mm (1.6 in x 0.8 in) reference ground plane. VSWR Figure 1 provides the voltage standing wave ratio (VSWR) across the nSP250 bandwidth. The target 2.4 GHz and 5.8 GHz ISM bands used for WiFi/WLAN are highlighted, as is the U-NII band. VSWR describes the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency. Reflected power is also shown on the right-side vertical axis as a gauge of the percentage of transmitter power reflected back from the antenna. 5 40 4 30 3 20 2 10 1 1 0 2.0 2.5 3.0 3.5 4.0 4.5 5.0 5.5 6.0 Frequency (GHz) Figure 1. nSP250 VSWR with Frequency Band Highlights 2 VSWR 2.400 2.500 5.150 5.5.250250 5.5.350350 5.5.470470 5.5.725725 5.875 Reflected Power (%)
