1. 1 Introduction The Sierra Wireless EM9190 Embedded Module is a FirstNet-ready (B14 LTE) M.2 module and provides 5G NR Sub-6G, 5G mmWave, 4G LTE advanced Pro, 3G (HSPA+, UMTS), and GNSS connectivity for a wide range of devices and purposes, including business, personal, and portable computing and communication devices, IoT devices, M2M applications and industrial use cases.
2. 2.1. Power 2 Power Supply The host provides power to the EM9190 through multiple power and ground pins as summarized in Table 2-1. The host must provide safe and continuous power (via battery or a regulated power supply) at all times; the module does not have an independent power supply, or protection circuits to guard against electrical issues. Table 2-1 Power and Ground Specifications Name Pins VCC (3.3V) 2, 4, 24, 38, 68, 70, 72, 74 GND Specification Min Typ Max Units Voltage range 3.

AirPrime EM9190 Hardware Integration Guide 3.1. RF Specifications RF Connections When attaching antennas to the module: Sub-6G /GNSS connectors: Use RF plug connectors that are compatible with the following RF receptacle connectors: I-PEX (20449-001E (MHF4)). Match coaxial connections between the module and the antenna to 50Ω. Minimize RF cable losses to the antenna; the recommended maximum cable loss for antenna cabling is 0.5 dB.
AirPrime EM9190 Hardware Integration Guide RF Specifications Antenna cables should be routed, if possible, away from noise sources (switching power supplies, LCD assemblies, etc.). If the cables are near the noise sources, the noise may be coupled into the RF cable and into the antenna. See Interference from Other Wireless Devices.
AirPrime EM9190 Hardware Integration Guide RF Specifications The Tx power and corresponding broadband noise of other wireless devices may overload or increase the noise floor of the module’s receiver, resulting in Rx desense. The severity of this interference depends on the closeness of the other antennas to the module’s antenna. To determine suitable locations for each wireless device’s antenna, thoroughly evaluate your host device’s design. 3.4.2.
AirPrime EM9190 Hardware Integration Guide RF Specifications To determine the extent of any receiver performance desensitization due to self-generated noise in the host device, over-the-air (OTA) or radiated testing is required. This testing can be performed by Sierra Wireless or you can use your own OTA test chamber for in-house testing. 3.5.1.

AirPrime EM9190 Hardware Integration Guide Parameter Requirements RF Specifications Comments Measured at the RF connector. Includes mismatch losses, losses in the matching circuit, and antenna losses, excluding cable loss. Sierra Wireless recommends using antenna efficiency as the primary parameter for evaluating the antenna system. Peak gain is not a good indication of antenna performance when integrated with a host device (the antenna does not provide omni-directional gain patterns).
