1. Introduction
WIFI-2-V897EA1 is based on Marvell 88W8897,complied with IEEE 802.11a/b/g/n/ac. The Module is a
highly integrated MAC/BBP and 2.4/5GHz RF/PA/LNA single chip which supports a 866.7Mbps PHY
rate. The Module is designed to support standard-based features in the areas of security, quality of
service, and international regulations, giving end users the greatest performance anytime and in any
circumstance. This documentation describes the engineering requirements specification.
■ IEEE802.11ac (draft)compliant,2x2 MIMO spatial stream multiplexing with data rates up to
MCS9(866.7Mbps)
1.1 RF module Overview
The general HW architecture for the module is shown in Figure 1. This WLAN Module design is based
on Marvell 88W8897. It is a highly integrated single-chip MIMO(Multiple In Multiple Out) Wireless LAN
(WLAN) network interface controller complying with the 802.11ac specification over SDIO,PCIE,USB
and UART interface.. It combines a MAC, a 2T2R capable baseband, and RF in a single chip. The
88w8897 provides a complete solution for a high throughput performance wireless client .

7. Statement：
FCC Radiation Exposure Statement
Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
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
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.
FCC Radiation Exposure Statement
The modular can be installed or integrated in mobile or fix devices only. This modular be installed in any portable device, for example, USB dongle like
transmitters is forbidden. This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be
collocated or operating in conjunction with antenna or transmitter. If the FCC identification number is 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 label referring to the enclosed module. This exterior label can use
wording such as the following:” Contains Transmitter Module FCC ID: 2ACHK- V897EA1 Or Contains FCC ID: 2ACHK- V897EA1 when the module is installed
inside another device, the user manual of this device must contain below warning statements;1. 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.(2) This device must accept any interference received, including
interference that may undesired operation.2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's
authority to operate the equipment. The devices must be installed and used in strict accordance with the manufacturer’s instructions as described in the user
documentation that comes with the product. This device is intended only for OEM integrators under the followingconditions:1) The antenna must be installed
such that 20 cm is maintained between the antenna and user.2) The transmitter module may not be co-located with any other transmitter or antenna. Module
Antenna Type:
For 2.4GHz : Antenna 0: 1.8dBi, Antenna 1: 2.4dBi
