Note: R8 is the current-limiting resistance in order to ensure VRTC working normally. R8 ≥1kohm VRTC Current consumption < 2uA; C9 value can affect RTC hold time You can refer to the following formula to calculate the RTC hold time: T= (1.8-0.5)*C/1=1.3C, unit: s For example: If C9 use 100uF capacitance, the RTC can hold about 130s. Just don’t connect pin VRTC if no need RTC function. 5.2 ON/OFF and Reset 5.2.

Reference design: Figure 5- 5 POWER_OFF Reference Design 5.2.4 Reset Signal H350 wireless communication module supports external reset; it can restore the module to default settings through Reset signal. When Reset signal is Active Low by 100ms, the module will reset and restart. When users reset the module, PMU inside the module is still on. Note: Reset signal is sensitive, when PCB layout, please keep it away from radio frequency interference, add debouncing capacitor near the module end is recommended.

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.

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).
