5. This module must not transmit simultaneously with any other antenna or transmitter

6. The host end product must include a user manual that clearly defines operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines.

For portable devices, in addition to the conditions 3 through 6 described above, a separate approval is

required to satisfy the SAR requirements of FCC Part 2.1093 If the device is used for other equipment that separate approval is required for all other operating

configurations, including portable configurations with respect to 2.1093 and different antenna

configurations. For this device, OEM integrators must be provided with labeling instructions of finished products.

Please refer to KDB784748 D01 v07, section 8. Page 6/7 last two paragraphs:

A certified modular has the option to use a permanently affixed label, or an electronic label. For a permanently affixed label, the module must be labeled with an FCC ID – Section 2.926 (see 2.2

Certification (labeling requirements) above). The OEM manual must provide clear instructions explaining

EM061K-GL_Hardware_Design

11 / 75

LTE-A Module Series
to the OEM the labeling requirements, options and OEM user manual instructions that are required (see next paragraph). For a host using a certified modular with a standard fixed label, if (1) the module’s FCC ID is not visible when installed in the host, or (2) if the host is marketed so that end users do not have straightforward commonly used methods for access to remove the module so that the FCC ID of the module is visible; then an additional permanent label referring to the enclosed module: “Contains Transmitter Module FCC ID: XMR2023EM061KGL/XMR2023EM061KGL2/XMR2023EM061KGL3” or “Contains FCC ID: XMR2023EM061KGL/XMR2023EM061KGL2/XMR2023EM061KGL3” must be used. The host OEM user manual must also contain clear instructions on how end users can find and/or access the module and the FCC ID. The final host / module combination may also need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device. The user’s manual or instruction manual for an intentional or unintentional radiator shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. In cases where the manual is provided only in a form other than paper, such as on a computer disk or over the Internet, the information required by this section may be included in the manual in that alternative form, provided the user can reasonably be expected to have the capability to access information in that form. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment. To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Supplier’s Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. IC Statement IRSS-GEN “This device complies with Industry Canada’s licence-exempt RSSs.

4 To meet this operating temperature range, you need to ensure effective thermal dissipation, for example, by adding passive or active heatsinks, heat pipes, vapor chambers, etc. Within the temperature range of -10 °C to +55 °Cthe
mentioned RF performance margins higher than 3GPP specifications can be guaranteed. When temperature goes beyond temperature range of -10 °C to 55 °C, a few RF performances of module may be slightly off 3GPP specifications. 5 To meet this extended temperature range, you need to ensure effective thermal dissipation, for example, by adding passive or active heatsinks, heat pipes, vapor chambers, etc. Within this range, the module remains the ability to establish and maintain functions such as voice, SMS, emergency call, etc., without any unrecoverable malfunction. Radio spectrum and radio network are not influenced, while one or more specifications, such as Pout, may undergo a reduction in value, exceeding the specified tolerances of 3GPP. When the temperature returns to the normal operating temperature level, the module will meet 3GPP specifications again.

The table below summarizes different operating modes of the module.

Table 6: Overview of Operating Modes

Mode
Full Functionality Mode
Minimum Functionality Mode Airplane Mode Sleep Mode
Power Down Mode

Details
Software is active. The module has registered on the Idle
network, and it is ready to send and receive data. Network is connected. In this mode, the power consumption Voice/Data is decided by network setting and data transfer rate. AT+CFUN=0 sets the module to a minimum functionality mode without removing the power supply. In this mode, both RF function and (U)SIM card are invalid. AT+CFUN=4 or driving W_DISABLE1# pin low will set the module to airplane mode. In this mode, the RF function is invalid. The module keeps receiving paging messages, SMS, voice call and TCP/UDP data from the network with its power consumption reduced to the minimal level. In this mode, the power management unit shuts down the power supply. Software is inactive, while all interfaces are inaccessible and the operating voltage (connected to VCC) remains applied.

NOTE For more details about the AT command, see document [3].

3.2. Sleep Mode
In sleep mode, DRX (Discontinuous Reception) of the module is able to reduce the power consumption to a minimum level, and DRX cycle index values are broadcasted by the wireless network. The figure below shows the relationship between the DRX run time and the power consumption in sleep mode. The longer the DRX cycle is, the lower the power consumption will be.

3.5.2. Reference Design for Power Supply
The performance of the module largely depends on the power supply design. The continuous current of the power supply should be 3 A at least and the peak current should be 4 A at least. In case of a slight difference between input and output voltages, use an LDO when supplying power to the module. In case of a large difference between input and desired output (typically 3.7 V) voltages, using a buck DC-DC converter is preferred.
The following figure shows a reference design for +5 V input power supply based on DC-DC converter.

NOTE
To avoid corrupting the data in the internal flash, do not cut off the power supply before the module is completely turned off, and do not cut off power supply directly when the module is working.

3.5.3. Voltage Stability Requirements
The power supply of the module ranges from 3.135 V to 4.4 V. Please ensure that the input voltage never drops below 3.135 V, otherwise the module will be powered off automatically. The following figure shows the maximum voltage drop during burst transmission in 3G/4G networks.

Voltage Drop 3.135 V

Voltage Ripple < 100 mV

Figure 6: Power Supply Limits During Burst Transmission
To decrease the voltage drop, two bypass capacitors of about 220 µF with low ESR (ESR = 0.7 ) should be used. To avoid disturbing the power supply, two multi-layer ceramic chip capacitor (MLCC) arrays also should be used due to their ultra-low ESR. It is recommended to use eight ceramic capacitors (1 µF, 100 nF, 33 pF, 10 pF) to compose the MLCC arrays, and to place these capacitors close to VCC pins. The width of VCC trace should be not less than 2.5 mm. In principle, the longer the VCC trace is, the wider it should be.
