Antenna Requirements
The antenna must specifications meet the following requirements

LTE/5G Sub-6 Antenna Requirements

Frequency Range	Depending by frequency band(s) provided by the network operator, the customer shall use the most suitable antenna for that/those band(s)
Impedance	50Ω
Input Power	> 24 dBm average power in LTE & 5G Sub-6
VSWR absolute max.	<= 10:1
VSWR recommended	<= 2:1

GNSS Receiver
The WM-H801UE integrates a GNSS receiver that could be used in Standalone mode and in A-GPS (assisted GPS), according to the different configurations.

Frequency Range	Wide-band GNSS: 1559–1606 MHz recommended GPS: 2.046 MHz BW NB GPS (centered on 1575.42 MHz) Glonass (GLO): ~ 8.3 MHz BW (1597–1606 MHz) BeiDou (BDS): 4.092 MHz BW (1559.05 – 1563.14 MHz) Galileo (GAL): 4.092 MHz BW (centered on 1575.42 MHz)
Impedance	50Ω
Gain	1.5 dBi < Gain < 3 dBi
Amplification	18 dB < Gain < 21 dB
Supply Voltage	3.1 V
Current consumption	20 mA Typical

GNSS RF Front End Design(TBD)
The WM-H801UE contains an integrated LNA and pre-select SAW filter. This allows the module to work well with a passive GNSS antenna. If the antenna cannot be located near the WM-H801UE, then an active antenna (that is, an antenna with a low noise amplifier built in) can be used with an external dedicated power supply circuit. GNSS receive path uses either the dedicated GNSS
connector or the shared Secondary #3 antenna connector.

Pin	Signal	I/O	Function	Comment
Turn On/Off
6	FULL_CARD_PWR_OFF_N	I	Module On/Off	1.8V/3.3V

FULL_CARD_POWER_OFF# signal is an Active Low input that is used to turn off the entire module. When the input signal is asserted high (≥1.19 V) the Module will be enabled. When the input signal is driven low signal (≤0.2 V), it will force the module to shut down.
The FULL_CARD_POWER_OFF# pin has internally pulled low with a weak pull-down 100 kΩ resistor. The input must be 3.3 V tolerant but can be driven by either 1.8 V or 3.3 V GPIO.

Mechanical Dimensions

Top and Bottom Views of the Module 

Mechanical Dimensions of the Module 

Module Stand-off(PAN NUT)
The modules will need a mechanical retention at the end of the board. The module specifies a 5.5 mm diameter Keep-out zone at the end for attaching a screw. This section provides a guideline for using a M2 x 0.4 mm screw with a shoulder stand-off.

 Recommended Main Board Hole
The recommended plated-hole sizes for the main board are:

• Drill size 4.3 mm
• Finish size 4.2 ±0.075 mm
• Pad size 6.5 mm

Electrical Ground Path
The module Stand-off and mounting screw also serve as part of the module Electrical Ground path.
The Stand-off should be connected directly to the ground plane on the platform. So that when the module is mounted and the mounting screw is screwed on to hold the module in place, this will make the electrical ground connection from the module to the platform ground plane.

Stand-off Guideline
A shoulder stand-off is a board-level SMT component that has a 2 x 0.4 thread. The height of the stand-off is determined by what connector is used.
* Our manual doesn’t provide a flat stand-off

Connector Height Descriptor	L2
H3.2	1.45 ± 0.03
H4.2	2.45 ± 0.03

*L2 depends on your M.2 connector height.

• Requirements for SMT
  • Polymide patch required for vacuum pick-up
  • Minimum thermal conductivity of 50 W/(mK) or greater
  • Material = Steel
  • Finish = Matte tin, 1.2 microns minimum average
  • Tape and reel

 Screw Guideline
Screw consideration should be made to usage model. The tolerances of the connector, module and stand-off allow for a gap to exist between the seating plane and the contact. the guidelines of a wafer-head style M2 screw are provided. This screw is intended for use only with the shouldered stand-off. The length is to be determined by the system design; 2 mm length supports L2=1.45 and 2.45 stand-off.

FCC Part 15.105 statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Regulatory notice to host manufacturer see KDB Publication 996369 D04 for guidance.
This module has been granted modular approval as below listed FCC rule parts.

Label and compliance information
End Product Labeling
The module is labeled with its own FCC ID. If the FCC ID are not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. In that case, the final end product must be labeled in a visible area with the following:
Contains FCC ID: 2A9FK-WM-H801UE

Information on test modes and additional testing requirements
OEM integrator is still responsible for testing their end-product for any additional compliance required with this module installed (for example, digital device emissions, PC peripheral requirements, additional transmitter in the host, etc.).

Additional testing, Part 15 Subpart B disclaimer
The final host product also requires Part 15 subpart B compliance testing with the modular transmitter installed to be properly authorized for operation as a Part 15 digital device.
