Multiple frequency, protocol, and functionality solutions for IoT connectivity continues to push the size and performance limit. To address this, we've developed a multi-band flexible solution using one antenna (p/n 0830AT54A2200). This solution covers Cellular (LTE), Sub-GHz (868/915MHz), GPS and/or GNSS (GLONASS), 2.4GHz (Bluetooth and/or WiFi) using 1 SMT Chip antenna and 2 six channel RF switches. The entire solution requires a PCB area of about 360mm2, making it very compact with industry-accepted radiated gain and efficiency in a 51x51mm board.
