Interference Statement
This device complies with 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 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 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.
FCC Caution:
Any changes or modifications not expressly
approved by the party responsible for compliance
could void the user's authority to operate this
equipment.
This transmitter must not be co-located or
operating in conjunction with any other antenna
or transmitter.
Radiation Exposure Statement:
This equipment complies with FCC radiation
exposure limits set forth for an uncontrolled
environment. This equipment should be installed

between the radiator & your body.
This device is intended only for OEM integrators
under the following conditions:
1) The antenna must be installed such that 20
cm is maintained between the antenna and users,
and
TPM10

Cat-M1 Module
2) The transmitter module may not be
co-located with any other transmitter or antenna.
As long as 2 conditions above are met, further
transmitter test will not be required. However, the
OEM integrator is still responsible for testing their
end-product for any additional compliance
requirements required with this module installed
IMPORTANT NOTE: In the event that these
conditions can not 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 can not 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.
End Product Labeling
This transmitter module is authorized only for use
in device where the antenna may be installed such
that 20 cm may be maintained between the
antenna and users. The final end product must be
labeled in a visible area with the following:
“Contains FCC ID: P27-TPM10”. The grantee's FCC
ID can be used only when all FCC compliance
requirements are met.
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.
RF typical circuit
The RF inter-connect called P1 is for example
purposes only. Depending on the antenna,
interfacing system will dictate the RF inter-connect.
Below picture is showing RF typical circuit.
LTE-ANT0 is the primary(main) antenna pin and
carries TX and RX signals. Connect 50 Ohm
transmission lines from this pins to the 50 Ohm
Primary Antenna/Antenna connetors.
The picture RF typical circuit shows, included in
the connection between ANT and the antenna
connectors, T-type network for matching.

Cat-M1 Module
1. Functional Overview
TPM10 module provides the interconnection between Cat-M1 networks and terminals.
Interconnection with Cat-M1
−
TPM10 module receives and processes signals sent from Cat-M1 networks,
and then sends commands or data to terminals for performing the
operation and maintenance (O&M).
−
The module receives data and commands from terminals, transferring
those data and commands to Cat-M1 networks, and then delivers them to
application servers (ASs).
Interconnection with terminals
−
TPM10 module reads and uploads terminal data to the Cat-M1 networks.
−
The module receives commands from the Cat-M1 networks and performs
O&M for terminals.
1.1. Block Circuit Diagram
TPM10 module is based on the SQN3330 Cat-M1 baseband and developed for 3GPP E-UTRA
and Wireless LTE Cat-M1 UE specification. The image below shows the module block
diagram:
TPM10

Cat-M1 Module
1.2. Main Module Components
The TPM10 includes the following components.
A. SQN3330
This module includes SQN3330 Cat-1 baseband, a complete dual band RF front end, memory
and required circuitry to meet 3GPP E-UTRA (Long Term Evolution - LTE, Release 13 set of
specifications) and Wireless LTE Cat-M1 UE specifications.
SQN3330 is a single-chip LTE Cat M1 solution, which is designed specifically for narrowband
IoT applications, including sensors, wearables, and other low data, low power M2M and IoT
devices.
B. RF
The RF matching circuit.
C. Power system
The main power supply is “VBAT1“ and its range is 3.1~4.5V while the “VSIM” power supply
(3.0V) is for external SIM circuit.
D. Clock in system
TPM10 is using 32KHz clock in the module system.

Cat-M1 Module
1.3. LTE Low Power Modes
This module will automatically enter in low-power mode. It can be woken from low power
mode by the following external sources:
SIM_DETECT input signal to cope with SIM card insertion into a SIM card connector with
built-in hardware detection. The default configuration to wake-up the module is a
low-to-high transition.
The RTS0 input signal whenever data traffic is initiated by the host connected to the
module UART0 with hardware flow control; The default configuration to wake-up the
module is a high-to-low transition.
Two dedicated input signal WAKE0 and WAKE1; The default configuration to wake-up the
module is on a high-to-low transition. This can be modified by software. As example, these
signals can be used to detect an alarm from an external IC such as a sensor. Software can
disable the wake-up functionality on these signals.
A subset of GPIO input signals: GPIO2, GPIO3, GPIO25, GPIO27, GPIO42; they are not
configured by default as wake-up source but software can configure them for future use.

The module has no electro-static discharge (ESD) protection measures, and its sensitive
pins need external ESD protection. Appropriate ESD measures need to be added during
the manufacturing/transporting/operation stages.

5. EMC
The signal integrity and power integrity issues caused by electromagnetic compatibility
(EMC) need to be considered when you use the module to design. Below are some
suggestions:
The coupling of the module and other digital chips must be deployed remotely as far as
possible, in order to avoid mutual interference.
The power supply (CSS), clock, high-speed digital signals, EMI components, and RF
simulation parts must be deployed remotely as far as possible.
The CSS, clock, high-speed digital signals, EMI components, and antennas must be
coupled remotely as far as possible in space.
During cabling routing, RF reference ground, digital and analog areas should be
separated, and all cables are routed in compliance with specified requirements to
avoid mutual coupling between lines.
The decoupling capacitor is placed near pins.
