WLM200N5-23ESD integrates an Atheros AR9280 chipset to create RF energy. The Atheros
AR9280 is an all CMOS, single chip solution for dual-band, multi-mode, IEEE 802.11a/n WLANs.
It integrates a 5GHz radio, analog-to-digital and digital-to-analog (ADC/DAC) converters, a
baseband processor and multi-protocol media access control.
For the AR9280’s transmitter, it combines baseband in-phase(I) and quadrature (Q) signals,
converts them to the desired frequency, and drives the RF signal off-chip. This RF signal is again
filtered by a low pass filter, before sending into a power amplifier chipset, which amplifies the RF
signal. For the AR9280’s receiver, it uses an integrated dual conversion architecture and requires
no off-chip intermediate frequency (IF) filters.
Users manual of the end product:
In the users manual of the end product, the end user has to be informed to keep at least 20cm
separation with the antenna while this end product is installed and operated. The end user has to be
informed that the IC radio-frequency exposure guidelines for an uncontrolled environment can be
satisfied. The end user has to also be informed that any changes or modifications not expressly
approved by the manufacturer could void the user's authority to operate this equipment. IC
statement is required to be available in the users manual: This Class B digital apparatus complies
with Canadian ICES-003.
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.
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 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. Since this may depend on the
