5V_TX (4.8V~5.3V). 5V_TX means providing power of internal power amplifier. And it is divided
because it can be affect to the other circuit such as audio by outbreak of TDMA ripple noise, which is
caused by peak current during TX burst.
5V_TX is supply power used at the intenal PA in the module, it is separated from VPWR, because the
ripple in a transmit burst is
The ripple noise level of the power supply has to be limited to 50mV RMS in the 1㎒ ~ 100㎒ frequency
range.
Required each of two power supplys specifications are described in follow.
3.1
VPWR
VPWR is main power source supplied at entire circuit except PA power in SAT module.
The suppled voltage range at VPWR is from 3.2V to 4.5V.
The internal ASIC in SAT module is detect voltage level of these pins.
If these pins are below 3.2V, module is power off, so when you design the power supply applications, it
must be connted with the power source be able to provide sufficient current to rated 350㎃
User can read to the voltage level of these pins as using AT command.
Power supply lines must be formatted to carry the rated 350㎃(3.7V) current and kept short as possible to
reduce lines impedance.
Bypass capacitors must be added to the power supply lines over 33㎌ MLCC (Multi-layer ceramic chip)
or tantalum capacitor of low ESR for best input voltage filtering and minimizing the interference with
other circuits caused by high input voltage spikes and small value ceramic capacitor in parallel beside of
B-to-B connector as possible.
The value of the bypass capacitors can be increased without any limit for better input voltage filtering.
3.2
5V_TX
5V_TX is main power source for internal PA (power amplifier) in SAT module.
In some case, the ripple in a transmit burst may cause voltage drops when current consumption rises to
typical peaks of 1.5A (5V), so the power supply must be able to provide sufficient current up to 1.5A.
These pins shouldn’t be drops below 4.8V. If voltage of these pins is below 4.8V, module will not
processing the call.
The best way to reducing voltage drops is using the low impedance power source including power supply
lines and ESR value of the bypass capacitors.
We recommend that you use linear regulators what has low ripple noise and good transient response as
source power.
5V_TX input capacitor depends on the impedance of the source supply and input power ripple.
To satisfy this high RMS current demand, two 150 ㎌ (10V) are required.
In parallel with these bulk capacitors, two 47 ㎌ (10V), low ESR (X5R) ceramic capacitors are added for
HF noise reduction.

3.3
Power supply solutions of various application
User should select power device by regarding the following items as suitting to the character of each
power when designs power supply.
1. Ripple noise should be ignorable
2. Transient response should be good quality
3. Whether output current enable to support enough current to each PIN
4. Whether accuracy is guaranteed
5. Whether PCB space suit to the condition required
6. Whether proper cost is required
There are some alternative devices for SAT module power supply solutions. The most common are
described in below.
1.
Linear voltage regulators (Section 5.3.1)
2.
Switched DC/DC converter (Section 5.3.2)
3.
1-cell Li-Ion battery (Section 5.3.3)
3.3.1 Linear voltage regulators
Linear regulators has good quality of ripple noise and output accuracy, so power supply with linear
regulators is easy to design, and the total cost for the components can be low, but efficiency is so bad

when the difference input voltage and output voltage is big.
Ideally if the desired output voltage is 5V and the input voltage is 15V, ideal 10V goes away as heat, so
efficiency is only 30%. Therefore linear voltage regulator is necessary to effective cooling element in case
of big power dissipations.
We recomed linear voltage regulators only use when the difference input voltage and output
voltage is below 1V
Figure 4 Ideally efficiency of linear voltage regurator
3.3.2 Switched DC/DC converter
A switched DC/DC converter is very often used when there are requirements for high efficiency.
If you design the power supply what input voltage is above 15V and output voltage only is 5V, you need
to the many cooling equipments because of a lot of heat. This problem can be resolved by using a
switched DC/DC converter of high effiency.
There are instead a lot of other things to consider when design with switched DC/DC converter.
1. Need to many parts of inductor, diode, big size capacitor etcs.
2. PCB artwork must be very well because around a switched DC/DC converter there are magnetic fields,
which can create disturbances to other electronic circuits.
3. Circuit is designed that it is suppressed the ripple noise created by switching of MOSFET.
3.3.3 Battery
1-cell Li-Ion battery is general power equipment which is mostly used at the handheld goods.

When using a Li-Ion battery the battery must be able to deliver all necessary power peaks to the SAT
module.
The pack incorporates a protection circuit capable of detecting overvoltage (protection against
overcharging), undervoltage (protection against deep discharging) and overcurrent. Overcurrent detecting
range should be setted as supply sufficient current
The internal resistance of the battery and the protection circuits should be as low as possible because
internal resistance is very proportioned the voltage drop. It is recommended not to exceed 100mΩ, even
under extreme conditions at low temperature.
The battery pack must be approved to satisfy the requirements of CE.
4 Control signals
There are 6-pins for control SAT module. It is pins for GM_ON, GM_OFF, /GM_RESET,
GM_WAKEUP, HOST_WAKEUP, GM_STATUS, and HOST_STATUS.

5 RTC backup battery interface
RTC (Real Time Clock) power of SAT module is supplied by VRTC pin of board-to-board connector.
VRTC is used power souce of internal RTC block and GPS chipset.
External backup battery should be connected at VRTC pin because there’s no supply of internal power in
VRTC pin. When RTC backup battery is not used, it should be connected with VPWR or VEXT. Because,
if this pin isn’t connected with any power source, SAT module doesn’t operate.
Electrical character of VRTC pin is as below.
Vmax = +5.5V
Vmin = +2.0V
Vnorm = +3V
Idd = 15 ㎂ (max)
6 UART interface
SAT module offers two UART ports. One provides 8-full-pins communications and the other one
provides only 4 pins.

7 USB interface
SAT module supports Revision 1.1 of Universal Serial Bus Specification.
8 AUDIO interface
8.1
CODEC selection
SAT module offers analog audio interface and digital audio interface.
Using or not of digital audio interface is decided by voltage level of CODEC_SEL pin.
If CODEC_SEL pin is ‘high’ level, then internal PCM CODEC is disabled and you can use external
PCM CODEC. If CODEC_SEL pin is ‘low’ level, then internal PCM CODEC is used. If you make
float CODEC_SEL pin, GEM module is using internal PCM CODEC.
When SAT module use internal PCM CODEC, you must make float DAI_DIN, DAI_DOUT, DAI_CLK,
and DAI_SYNC pins.
The spec for a pin being ‘High’ must be stated – the voltage rise time etc.
8.2
Digital Audio Interface
SAT module supply DAI for various audio applications.
The digital audio interface consist of data input (DAI_DIN), data output (DAI_DOUT), clock output
(DAI_CLK), and frame sync. (DAI_SYNC).
DAI_CLK : generated as 2.048MHz clock from SAT module.
DAI_SYNC : generated as 8kHz clock from SAT module.
DAI_DIN : received to 16-bits data from MSB bit to LSB bit at rising edge of clock.
DAI_DOUT: transmitted 16-bits data from MSB bit to LSB bit at rising edge of clock.
9 SIM card interface
SAT module requires a SIM card to operate in SAT mode (except for emergency call).
Support to the standard plug-in SIM card as defined in ETSI standard GSM 11.11, as modified by GSM 11.12.
Both 1.8V/3.0V and 3.0V only SIM cards are supported.

14HEAT DISSIPATION
14.1
Installation method of Heat Sink
The proper method of heat dissipation to avoid overheating is necessary when SM-2500 is used
in the closed space. Installation of HEAT SINK is recommended between PCB and SM-2500 as
shown in the following figure.
Figure 5 Installation method of Heat Sink
14.2
Guide of HEAT SINK and PCB design
The thickness of HEAT SINK should be changed depending on MATED HEIGHT as shown in
the following figure.
The parts should not be located on the PCB surface including B2B connector contacting with
Heat sink for SM-2500 and VIA hole during PCB design should be created on PCB as many as
possible for good heat dissipation regarding the PCB area shown in the following figure.

Figure .Guide of HEAT SINK and PCB design
The housing or case including SM-2500 and Heat Sink should be the material having good
thermal conductivity such as Aluminum and keep a good thermal contact between SM-2500 and
Heat Sink, and between the Heat Sink and outside housing.
