Surface-mount antenna targets LTE, LTE-M, and NB-IoT
Linx Technologies has introduced the Splatch® SP610 surface-mount embedded antenna for LTE cellular applications, including LTE-M (Cat-M1) and NB-IoT cellular Internet of Things (IoT) uses.

A mere 10-mm by 40-mm and just 2.8-mm high, the surface-mount SP610 antenna achieves exceptional performance in the more challenging 700 MHz bands as well as common higher-frequency bands. Like all Splatch antennas, the SP610 is designed to accommodate close proximity effects from interferers such as other solution components or the human body. This combination of small size and robust performance makes it especially well-suited for cellular IoT applications.

The SP610 targets North American cellular carriers for all LTE applications with excellent performance in the 700 MHz frequency bands favored by Verizon, AT&T and T-Mobile, while providing strong performance in 800 MHz, 900 MHz and over 1-GHz bands used by carriers, worldwide. Additionally, the antenna provides full band support for LTE-M and NB-IoT applications which use sub-1 GHz frequencies to achieve longer range, and often use frequency band edges to avoid other cellular traffic.

“Many antennas, particularly from our European competitors, are marketed as LTE antennas with sub-1 GHz range labeled as 698 MHz to 960 MHz. In fact, these antennas only perform well in bands from 791 MHz or even 824 MHz to 960 MHz which are more euro-centric, and they perform marginally at the 700 MHz bands where leading US carriers have deployed LTE networks,” said Linx Technologies President and CEO, Tolga Latif. “As the cellular IoT technologies, LTE-M and NB-IoT, take hold it is especially important that embedded LTE antennas provide edge-to-edge frequency support for low LTE bands. The SP610 does this, providing significantly better total radiation efficiency than competitor’s LTE antennas at 698 MHz.”
