REGULATORY DOMAIN SUPPORT

• Domain support but not currently certified for – TBD

MODULE INSTALLATION GUIDANCE

PCB Layout on Host PCB – General

Checklist (for PCB):

• MUST locate NX040 module close to the edge of PCB (mandatory for the 453-00175 for on-board PCB trace antenna to radiate properly).
• Use solid GND plane on inner layer (for best EMC and RF performance).
• All module GND pins MUST be connected to host PCB GND.
• Place GND vias close to module GND pads as possible.
• Unused PCB area on surface layer can flooded with copper but place GND vias regularly to connect the copper flood to the inner GND plane. If GND flood copper is on the bottom of the module, then connect it with GND vias to the inner GND plane.
• Route traces to avoid noise being picked up on VBAT, VLIM, VBUS supply and AIN (analog) and SIO (digital) traces.
• Ensure no exposed copper is on the underside of the module (refer to land pattern of NX040 development board).

PCB Layout on Host PCB for the 453-00175

Antenna Keep-Out on Host PCB

The 453-00175 has integrated PCB trace antennas and their performance is sensitive to host PCB. It is critical to locate the 453-00175 on the edge of the host PCB (or corner) to allow the antennas to radiate properly. Refer to guidelines in section PCB land pattern and antenna keep-out area for the 453-00175. Some of those guidelines repeated below.

• Ensure there is no copper in the antenna keep-out area on any layers of the host PCB. Keep all mounting hardware and metal clear of the area to allow proper antenna radiation.
• For best antenna performance, place the 453-00175 module on the edge of the host PCB, preferably in the edge center.
• The NX040 development board has the 453-00175 module on the edge of the board (not in the corner). The antenna keep-out area is defined by the NX040 development board which was used for module development and antenna performance evaluation is shown in Figure 1, where the antenna keep-out area is 10.5 mm high, 53.5 mm wide; with PCB dielectric (no copper) height 1.6 mm sitting under the 453-00175 PCB trace antenna.
• The 453-00175 module on-board PCB trace antennas are tuned when the 453-00175 is sitting on development board (host PCB) with size of 85.6 mm x 53.5 mm x 1.6 mm. The development board PCB extends 3.1 mm beyond the edge of the 453-00175 module. This PCB extension is not required and removal will have a small effect on the antenna.
• A different host PCB thickness dielectric will have small effect on antenna.

Host PCB Land Pattern and Antenna Keep-out for the 453-00175 Notes:

__

Note 1

| Ensure there is no copper in the antenna ‘keep out area’ on any layers of the host PCB. Also keep all mounting hardware or any metal clear of the area (Refer to 12.2.2) to reduce effects of proximity detuning the antenna and to help antenna radiate properly.
---|---
__

Note 2

| For the best on-board antenna performance, the module 453-00175 MUST be placed on the edge of the host PCB and preferably in the edge center of the host PCB wuth the antenna “Keep Out Area” is extended on the host board as done on the NX040 development board in Figure 1.
Note 3| Ensure that there is no exposed copper under the module on the host PCB.
Note 4| You may modify the PCB land pattern dimensions based on their experience and/or process capability.

Antenna Keep-Out and Proximity to Metal or Plastic

Checklist (for metal /plastic enclosure):

• Minimum safe distance for metals without seriously compromising the antenna (tuning) is 40 mm top/bottom and 30 mm left or right.
• Metal close to the 453-00175 PCB trace antennas (bottom, top, left, right, any direction) will have degradation on the antenna performance. The amount of that degradation is entirely system dependent, meaning you will need to perform some testing with your host application.
• Any metal closer than 20 mm will begin to significantly degrade performance (S11, gain, radiation efficiency).
• It is best that you test the range with a mock-up (or actual prototype) of the product to assess effects of enclosure height (and materials, whether metal or plastic).

External Antenna Integration with 453-00174

Please refer to the regulatory sections for FCC, ISED, EU, RCM, KC, and Japan for details of use of NX040-with external antennas in each regulatory region.
