H380 wireless communication module supports USB 2.0. It should install USB driver before use on
PC. After H380 module plugged into the PC, the USB can enumerate seven ports:

One 3G Modem/AT port for data transmission

Three ports for sending AT Command

One port for trace LOG information

Two ports reserved currently.
5.4.2 USB Interface Application
Reference Design as follow:
Figure 5- 6 USB Interface Reference Design
The capacitor of TVS(T101 and T102) must be less than 1pF. VUSB power supply has been
connected internal, so the VBUS pin of HOST can float.USB_D+ and USB_D- are high speed differential
serial signals, the highest transmit speed is up to 480 Mbps.
PCB Layout note:

USB_D+ and USB_D- signals trace same length, parallel, as short as possible.

USB_D+ and USB_D- should be isolated by Ground in same and adjacent layer. It is better for USB
performance when adding more GND VIA.

USB2.0 signal should trace near the Ground layer of PCB.

Impedance control of USB differential signals is 90 ohm.

USB signal should keep away from any strong noise signal like power supply etc.

Note:

For improving EMC performance, SIM card connector should be closed to module



The interface need ESD protection, ESD should be closed to SIM card pin

USIM_DATA is already pulled up(4.7K ohms) inside the module
SIM_DETECT support SIM hot plug, high level activated default (detect level can be changed by AT
command). If high level is detected, it means SIM card is inserted.
5.5.3 USIM Design Notice
The SIM interface and signals design is extremely important.
There are several design guidelines that must be followed:

The signals of the SIM card layout should be away from any possible EMI noise, such as RF antenna
and digital switching signals.

To ensure signal integrity, the length between SIM interface signals and module should not exceed
100 mm

To avoid crosstalk between USIM_CLK and USIM_IO, it is recommended to route them separately on
the application board, and preferably isolated by Ground layer.
H380 M.2 Series Module Hardware User Manual
page 28 of 41
The SIM card signals should be protected by ESD component(low capacitance capacitor, such as

Zener diode). The recommended part no of ESD component is AVR-M1005C080MTAAB (TDK). ESD
component should layout with SIM connector closely.
5.5.4 USIM Hot Plug
H380 supports the detection function of SIM status,and this function can realize SIM hot plug.
5.5.4.1 Hardware Connection
SIM hot plug function need support of SIM_DETECT signal.
When no SIM card, SIM_DETECT is low level; insert SIM, SIM_DETECT is high level.
Explanation:
1) For normally closed SIM connector circuit, as shown in Figure 5-7.SIM_DETECT connects Pin8 (SW2)
of U2, Pin7 (SW1) short GND. When there is no SIM card, SW2 and SW1 short, SW2 is low level. When
SIM card inserted, SW1 and SW2 disconnect, SIM_DETECT is pulled high.
2) For normally open SIM connector circuit, as shown in Figure 5-8. SIM_DETECT connects Pin8 (SW2)
of U2, and it also be pulled low by 47K ohms resistor. Pin 7 is pulled high by 4.7K ohms resistor. When no
SIM card, SW2 and SW1 disconnect, SW2 is low. After SIM inserted, SW2 and SW1 short, SIM_DETECT
is pulled high.
5.5.4.2 Software Configuration
“+MSMPD” AT command control SIM card hot plug function on/off.
AT+MSMPD=0, SIM card hot plug deactivated. Module does not detect SIM_DETECT signal.
AT+MSMPD=1, SIM card hot plug activated. Module support SIM hot plug by SIM_DETECT pin
signal status.
SIM_DETECT High level, SIM card is present, module registers the network automatically.
SIM_DETECT Low level, SIM card is absent, module drops out the network.
Note: The “+MSMPD” default value is “1”. SIM_DETECT is only used for SIM card hot plug detection,
Module don’t detect SIM_DETECT signal at the first startup(it means the module will read SIM card data
and register network at the first startup, no matter pin SIM_DETECT is high or low).
5.6 Digital Audio

7.2 RF PCB Design
7.2.1 Impedance Design
The impedance of RF should be matched 50 ohm.
7.3 Antenna Design
7.3.1 Main Antenna Design Requirements
(1) Antenna Efficiency
Antenna efficiency is the ratio between antenna input power and radiation power. The radiation power of
an antenna is always lower than the input power due to the following factors: return loss, material loss,
H380 M.2 Series Module Hardware User Manual
page 37 of 41
and coupling loss.
Efficiency of the master antenna > 40% (–4dB)
(2) S11 or VSWR
S11 (return loss) indicates the degree to which the input impedance of an antenna matches the reference
impedance (50 ohm). S11 shows the resonance feature and impedance bandwidth of an antenna. Voltage
standing wave ratio (VSWR) is another expression of S11. S11 relates to the antenna efficiency. S11 can
be measured by vector analyzer.
S11 of the master antenna < –10 dB
(3) Polarization
The polarization of an antenna is the orientation of the electric field vector that rotates with time in the
direction of maximum radiation.
Linear polarization is recommended: it would be better if the polarization direction of diversity antenna is
different from main antenna.
(4) Radiation Pattern
Radiation pattern refers to the directional dependence of the strength of radio waves from the antenna or
other source.
The radiation pattern of half wave dipole antennas is the best for wireless terminals. If it is built-in antenna,
PIFA antenna is recommended:
Antenna area (H x W x L): 6mm x 10mm x 100mm. PIFA or IFA antenna is recommended.
Radiation Pattern: Omni-directional
(5) Gain and Directivity
The directivity of the antenna is the electromagnetic field strength of the electromagnetic wave in each
direction. An antenna's power gain is a key performance Figure which combines the antenna’s directivity
and electrical efficiency.
Recommended antenna gain ≤ 2.5dBi
(6) Interference
Besides the antenna performance, the interference on the PCB board also affects the radio performance
(especially the TIS) of the module. To guarantee high performance of the module, the interference
sources on the user board must be properly controlled. On the PCB board, there are various interference
sources that can affect the module, such as the speaker, LCD, CPU, FPC trace and audio circuits, the
power supply should be far away from antenna, notice isolation, shield and filtering processing issues.
(7) TRP/TIS
TRP (Total Radiated Power):

The design methods of diversity antenna and main antenna are the same, its efficiency indicators allows
to reduce 3dB.
The isolation between main antenna and diversity antenna should be higher than 12dB.

manual:
This device complies with Part 15 of 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 cause
undesired operation.
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-only exposure condition must not
exceed 2.5dBi in the cellular band and 2.5dBi in the PCS band.
A user manual with the end product must clearly indicate the operating requirements and conditions
that must be observed to ensure compliance with current FCC RF exposure guidelines. The end product
with an embedded H380.
Module may also need to pass the FCC Part 15 unintentional emission testing requirements and be
properly authorized per FCC Part 15.
Note: If this module is intended for use in a portable device, you are responsible for separate
approval to satisfy the SAR requirements of FCC Part 2.1093.
