aNSONIC NXLD RF Module
NXs LD US/EMEA
The NXLD RF module is a completely new design. The footprint is very small, but the logic & I/O capabilities remain compatible to our flagship NX1. The RF part is designed for the 868/915MHz area with up to 22dBm output power and Long Range DSSS coding.
The higher power compensates for the loss of penetration properties of twice
the frequency compared to 434MHz. Furthermore, the use of long-range coding
methods results in an additional gain in range.
One challenge compared to our 434MHz solutions is the current consumption of
up to 130mA, which effects especially small battery driven devices.
Therefore, these modules target larger size transmitters with according
battery power and/or less frequent transmission events.
This module is FCC certified under part15-modular approach and can be used as- is (together with one of the two certified antennas) at 915MHz in the US without any new certification process. Customer only has to fill a so-called SDoC (self-declaration, pointing on the FCC number of that module).
Another option is to use the module in EMEA in the 868MHz range, where the module operates in a slot which is allowed to operate at 22dBm output power.
Customers need to order the frequency range area according to their needs.
This module shall be operated in packet mode only, operated by the UART connection.
This module shall be operated in packet mode only, operated by the UART
connection.
NX1 -adapter/carrier:.
Mechanical compatibility to our NX1-modules can be achieved easily with these
carrier boards.
Using it makes this module a 1:1 replacement to NX1 (packet mode only)

2.2 List of applicable FCC rules
FCC 47 CFR Part 15C ‘modular transmitters’
2.3 Specific operational use conditions
Usage is only allowed if the validated antennas, described in this manual, are
used. Any other usage requires new FCC certification
2.4 Limited module procedures
Not applicable
2.5 Trace antenna designs
Not applicable
2.6 RF exposure considerations
LORA module max. output: 22dBm Antenna gain: -3dBm
➔ Resulting max e.i.r.p. :19dBm = 0.08W
E.i.r.p. is less than the RF exposure evaluation exempted power. So RF
exposure evaluation is not required.
The antenna(s) used for this transmitter must be installed to provide a
separation distance of at least
20 cm from all persons and must not transmit simultaneously or operated in
conjunction with any other antenna or transmitter within a device. End-users,
installers and OEM integrators must be provided with antenna installation
instructions and transmitter operating conditions for satisfying RF exposure
compliance
2.7 Antennas
Applicable antennas are described in this document. Those are part of the FCC
certification.
2.8 Label and compliance information
This module falls into the FCC 47 CFR Part 15C ‘modular transmitters’.
Operation in US-FCC is
permitted due to according certification. Import to US is allowed if customers
product refer to ‘contains
FCC ID: 2A28Q-NXLD’ and according use.
2.9 Information on test modes and additional testing requirements not
applicable
2.10 Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for the specific rule parts
listed on the grant.
The host product manufacturer is responsible for compliance to any other FCC
rules that apply to the host not covered by the modular transmitter grant of
certification.
