  • Page 5: Introduction

    Introduction The Sierra Wireless EM7690 Embedded Module is a FirstNet-ready (B14 LTE) M.2 module and provides 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.

  • Page 6: Power

    Power 2.1. Power Supply The host provides power to the EM7690 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.

Note: There is no explicit list of antennas required in the application. The PWB-6-60-RSMAP Wide Band For detailed electrical 4G Terminal Paddle Antenna has been verified as a reference.

  • Page 11: Interference And Sensitivity

    AirPrime EM7690 Hardware Integration Guide RF Specifications  Prevent noise leakage by establishing a very good ground connection to the module through the host connector.  Connect to system ground using the ground hole shown in Figure 3-1.  Minimize ground noise leakage into the RF. Depending on the host board design, noise could potentially be coupled to the module from the host board.

  • Page 12: Methods To Mitigate Decreased Rx Performance

    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. Sierra Wireless’ Sensitivity Testing and 3.5.1.
