WS8465DLS is a high-performance LoRa serial module supporting multiple frequency bands, featuring long communication distance and extremely low low power mode current, designed and manufactured by Chengdu Silent Smart Technology Co.
On-board low ripple rejection ratio (PSRR) LDO, effectively reducing the impact of power supply on RF performance.
High-performance RF filter added to the transmitter link to effectively suppress high harmonics
Internal SAW+LNA+SAW combination effectively suppresses out-of-passband interference while further improving reception sensitivity;
Adopt high precision, high stability, low temperature drift, wide temperature complementary active crystal oscillator TCXO.
All RF links use high Q wirewound inductors.
Communication port, power port, antenna port to add ESD
Supports license-free ISM 433MHz band and 470MHz meter reading band.
Adopts LoRa spread spectrum technology, which has strong anti-interference performance and long communication distance.
Supports users to set their own communication keys, which cannot be read, greatly improving the confidentiality of user data.
Supports up to 158mW (about 22dBm) of transmit power.
Adding RF filter to the transmitter link to effectively suppress high harmonics.
SAW+LNA+SAW for receiving link to reduce out-of-band interference and increase receiving sensitivity.
On-board high-precision, high-stability, low-temperature-drift, wide-temperature complementary active crystal oscillator TCXO
Add ESD to communication port, power port and antenna port.
Support AT command configuration
Support Modbus programmable register read/write operation, flexibility to customize the product function.
Supports Wake-on-Air, i.e. ultra-low power consumption, suitable for battery-powered applications.
Support transparent transmission, fixed-point transmission, broadcast transmission, channel monitoring, wireless relay and other functions.
