The layout design of this circuit on the AP board should comply with the USB 2.0 high speed protocol, With differential lining and impedance control to 90 ohm. 5.5 UART Interface 5.5.1 UART Interface Description H350 wireless communication module provides two UART, one is 8 wire serial bus interface, and the other is a 2 wire serial bus interface. 8 wire serial bus interface (UART1) supports flow control; users can download software or send/receive AT through UART1. 2 wire serial bus interface (UART2) supports a few AT Commands. Note: UART2 only supports some common query functions. UART2 doesn’t support hardware flow control, no CTS, RTS, DTR, DSR, DCD, RI pin.

When you design: Level shift from 1.8V to 3.3V, SN74LVC2G07 is recommended. When UART1 communicating with PC, first translates from 1.8V to 3.3V, and then uses SP3238 to translate. When UART2 communicating with PC, first translates from 1.8V to 3.3V, and then uses SPIEX3232EEA to translate level. Notice the signal direction when translate level. 5.5.3 Ring Indicator UART1_R1 is used for indicating incoming call and SMS, sending pulse to host application program.

H350 LGA Serials Module Hardware User Manual Page 34 of 43 5.6.2.2 Normally Open SIM Circuit Design Reference Design: Figure 5- 9 Normally Open SIM Interface Reference Design Normally Open SIM: 1)Pull out SIM card, pin 7 and pin 8 are disconnected. 2)Inset SIM card, pin 7 and pin 8 are shorted. Note: For better EMC performance, SIM card holder should be close to module Filtering capacitor should be close to SIM card pin The interface need add ESD protection, ESD should be close to SIM card pin USIM_IO is already pulled up inside the module USIM_CD 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. 5.6.3 USIM Design Notice The SIM interface and signals design is extremely important. There are several design guidelines that must be followed: H350 LGA Serials Module Hardware User Manual Page 35 of 43 The layout signals of the SIM card should be away from any possible EMI interference sources, such as the 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 a surrounding ground plane. The SIM card signals should be protected from ESD using very low capacitance protective elements (like Zener diode). The recommended part no of ESD is AVR-M1005C080MTAAB (TDK). ESD component should layout with SIM hold closely. 5.6.4 USIM Hot Plug H350 supports SIM hot plug. 5.6.4.1 Hardware Connection SIM hot plug function interacts with USIM_CD signal. When no SIM card, USIM_CD is low level; insert SIM, USIM_CD is high level. Explanation: For normally closed SIM card circuit, as shown in Figure 5-8, USIM_CD connects Pin8 (SW2) of U2, Pin7 (SW1) connects GND. When there is no SIM card, SW2 and SW1 are shorted, so, SW2 is low level, when insetting SIM card, SW1 and SW2 are disconnected, USIM_CD is pulled up. For normally open SIM card circuit, as shown in Figure 5-9, USIM_CD connects Pin8 (SW2) of U2, and it also connects GND with 47K resistor, Pin 7 is pulled up with 47K resistor. When no SIM card, SW2 and SW1 are disconnected, so SW2 is low level, after inserting SIM, SW2 and SW1 are shorted, USIM_CD is pulled up. 5.6.4.2 Software Configuration “+MSMPD” AT command defines the SIM card status detection feature. When set AT+MSMPD=0, the SIM detected feature deactivated. Module does not detect USIM_CD signal. When set AT+MSMPD=1, the SIM detected feature activated. USIM_CD pin can test whether SIM card is onsite or not. SIM_CD is High level, SIM card is onsite, and module registers the network automatically. SIM_CD is Low level or not connected, SIM card is offsite and module drops out the network. Note: The +MSMPD default value is “1”. USIM_CD is only used for SIM card hot plug detecting, Module won’t detect SIM_CD at the first starting (it means the module will read SIM card data and register network at the first time starting, no matter pin SIM_CD is high level or low level).

The shorter the better, insert loss is less than 0.2dB; impedance is less than 50ohm. It is to mount H350 module and antenna connector to the same side of layout. Add a π-type circuit (two parallel device ground pin directly to the main land) for antenna matching. Figure 7- 1π-type Circuit 7.2.2 Impedance The RF lines impedance should not exceed 50 ohm. H350 LGA Serials Module Hardware User Manual Page 41 of 43 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, 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 the 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. 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.
