PAGE 33
FN980 Family HW Design Guide Information – The current consumption of FN980m can be too much different according to mmWave antenna module. The budget of power supply chain should be over 4A@3.3V without mmWave antenna module to operate FN980m without any malfunction caused by the power supply. The peak current of FN980m with mmWave antenna will be addressed later.
PAGE 34
FN980 Family HW Design Guide And it reduces the probability of failure and does not adversely affect the use of the module, and greatly extends the operation time with maximum performance. For more details, please refer to thermal design guideline. Information – FN980 Family supports various RAT such as 3G, 4G, 5G Sub6 and mmW. Based on RF transmission mode, FN980 Family can consumes a lot of current. Therefore proper thermal designs to dissipate heat well is essencial.
PAGE 35
FN980 Family HW Design Guide  The protection diode must be placed close to the input connector where the power source is drained.  The PCB traces from the input connector to the power regulator IC must be wide enough to ensure that no voltage drops occur during the 4A current peaks.  The PCB traces to FN980 Family and the bypass capacitor must be wide enough to ensure that no significant voltage drops occur when the 4A current peaks are absorbed. This is needed for the same above-mentioned reasons.

PAGE 41
FN980 Family HW Design Guide Information – To verify if the FN980 Family has powered up properly, please check through below explanation: * Monitoring BOOT_OK(Shutdown indicator) pin. When the status translates to high, module is completely boot. To use Boot OK (Shutdown indicator), shutdown indication function must be enabled through AT#SHDNIND command (Refer to the AT Reference guide document).
PAGE 42
FN980 Family HW Design Guide Graceful Shutdown by FULL_CARD_POWER_OFF_N 6.3.2. Fast Shutdown For a quicker shutdown of the FN980 Family module, the host can use the fast shutdown function. Fast shutdown can be triggered by:  GPIO 6.3.2.1. Fast Shutdown by GPIO If properly configured, one of GPIO lines can be used as Fast Shutdown Trigger. Once the Fast Shutdown Trigger senses a HIGH to LOW transition, fast shutdown is triggered.
PAGE 43
FN980 Family HW Design Guide Information – Using a Fast shutdown without shutdown indicator function, FULL_CARD_POWER_OFF_N pin should be controlled to prevent the FN980 Family module rebooting. For more information, please refer to AT Commands Reference Guide and SW User Guide document. Fast Shutdown by GPIO (*SHDNIND Enable, Optional) Information – *Shutdown Indicator is optional function and disabled by default. Host can verify the module entered OFF state by Shutdown Indicator pin.
PAGE 44
FN980 Family HW Design Guide Warning – Not following the recommended shut-down procedures might damage the device and consequently void the warranty. Reset Device reset can be achieved as follows: • 6.4.1. Unconditional Reset using the SYS_RESIN_N Unconditional Hardware Reset To unconditionally restart the FN980 Family module, the SYS_RESIN_N pin must be asserted low more than 1 second and then released.
PAGE 45
FN980 Family HW Design Guide Information –Unconditional Hardware Reset must be used only as an emergency exit procedure, and not as a normal power-off operation. Information – Do not use any pull-up resistor on the RESET_N line or any totem pole digital output. Using a pull-up resistor may cause latchup problems on the FN980 Family power regulator and improper functioning of the module. The RESET_N line must be connected only in an open-collector configuration.

FN980 Family HW Design Guide Information This device is to be used only for mobile and fixed application. 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 co-located or operating in conjunction with any other antenna or transmitter. End-Users must be provided with transmitter operation conditions for satisfying RF exposure compliance.

FN980 Family HW Design Guide Gain 1.5 dBi < Gain < 3 dBi Impedance 50 Ohm Amplification 18 dB < Gain < 21 dB Supply Voltage 3.1 V 7.5.1. GNSS RF Front End Design The FN980 Family contains an integrated LNA and pre-select SAW filter. This allows the module to work well with a passive GNSS antenna. If the antenna cannot be located near the FN980 Family, then an active antenna (that is, an antenna with a low noise amplifier built in) can be used with an external dedicated power supply circuit.
