Compliance Information

FCC Compliance:

FCC Compliance Statement: 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. This device must accept any interference received, including
interference that may cause undesired operation. Product that is a radio transmitter is
labeled with FCC ID.

FCC Caution:
(1)Exposure to Radio Frequency Radiation. This equipment must be installed and operated in
accordance with provided instructions and 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 be
collocated or operating in conjunction with any other antenna or transmitter. End-users and
installers must be provided with antenna installation instructions and transmitter operating
conditions for satisfying RF exposure compliance.

(2)Any changes or modifications not expressly approved by the grantee of this device could
void the user's authority to operate the equipment.

(3)This Transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.

(4)Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user authority to operate the equipment.

(5) The modules FCC ID is not visible when installed in the host, or
(6) if the host is marketed so that end users do not have straight forward commonly used
methods for access to remove the module so that the FCC ID of the module is visible; then
an additional permanent label referring to the enclosed module: Contains Transmitter Module
FCC ID: U8O-A9 or Contains FCC ID: U8O-A9

Important Notice to OEM integrators

1. This module is limited to OEM installation ONLY.

2. This module is limited to installation in mobile or fixed applications, according to Part

2.1091(b).

3. The separate approval is required for all other operating configurations, including portable
configurations with respect to Part 2.1093 and different antenna configurations

4. For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing
to verify compliance as a composite system. When testing the host device for compliance with
Part 15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart
B while the transmitter module(s) are installed and operating. The modules should be
transmitting and the evaluation should confirm that the module's intentional emissions are
compliant (i.e. fundamental and out of band emissions). The host manufacturer must verify
that there are no additional unintentional emissions other than what is permitted in Part 15
Subpart B or emissions are complaint with the transmitter(s) rule(s).

Antenna Installation

A9 has 4 antenna port：PRX antenna、DRX antenna、GPS antenna、wifi&BT antenna，as

below picture , all antenna ports have 50Ω impedance.

1.PRX antenna reference design

A9 kept πkind circuit in board for antenna , it can adjust impedance automatically

according to actual antenna tune status , so that it could get best output performance.
Main antenna will be cable type, as above picture, cable loss suggestion less than 1dbm,

antenna input impedance 50 (Ω), Voltage Standing Wave Ratio ≤2, gain can’t be more than

below target

Standalone Condition:

6 dBi in LTE B7

3 dBi in GSM 850/1900, WCDMA BAND 5, LTE B5/12/13/17
5 dBi in WCDMA BAND 2/4, LTE B2/4

2.DRX antenna reference design

A9 kept πkind circuit in board for diversity antenna , it can adjust impedance automatically

according to actual antenna tune status , so that it could get best output performance.
Antenna can be either cable type or spring type, as above picture, cable loss suggestion

less than 1dbm, antenna input impedance 50 (Ω), Voltage Standing Wave Ratio ≤2, gain can’t

be more than below target

Standalone Condition:

6 dBi in LTE B7

3 dBi in GSM 850/1900, WCDMA BAND 5, LTE B5/12/13/17
5 dBi in WCDMA BAND 2/4, LTE B2/4

3.Wifi&BT antenna reference design

A9 kept πkind circuit in board for Wifi&BT antenna, it can adjust impedance automatically

according to actual antenna tune status , so that it could get best output performance.
Antenna will be spring type. as above spring picture, antenna input impedance 50 (Ω),

Rev. 1

Voltage Standing Wave Ratio ≤2, gain can’t be more than below target

Standalone Condition:

6 dBi in BT, 2.4G WIFI, 5G WIFI

4. GPS antenna reference design

A9 kept πkind circuit in board for GPS antenna, it can adjust impedance automatically

according to actual antenna tune status , so that it could get best output performance.
antenna will be cable type, as above picture, cable loss suggestion less than 1dbm,

antenna input impedance 50 (Ω), Voltage Standing Wave Ratio ≤2, gain >0dbi

In addition

(1) The antenna must be installed such that 20 cm is maintained between the antenna and

users.

(2) The transmitter module may not be co-located with any other transmitter or antenna.
(3) To comply with FCC regulations limiting both maximum RF output power and human
exposure to RF radiation, the maximum antenna gain including cable loss in a mobile
exposure condition must not exceed:

Standalone Condition:

6 dBi in LTE B7, BT, 2.4G WIFI, 5G WIFI

3 dBi in GSM 850/1900, WCDMA BAND 5, LTE B5/12/13/17

5 dBi in WCDMA BAND 2/4, LTE B2/4

In the event that these conditions cannot be met (for example certain laptop configurations
or co-location) with another transmitter), then the FCC authorization is no longer considered
valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM
integrator will be responsible for re-evaluating the end product (including the transmitter)
and obtaining a separate FCC authorization.

Manual Information to the End User

The OEM integrator has to be aware not to provide information to the end user regarding how
to install or remove this RF module in the user’s manual of the end product which integrates
this module. The end user manual shall include all required regulatory information/warning as
show in this manual.
