Sub-1GHz ASK Modulation RF Receiver Module DL-RXP4303
Product Description
High Sensitivity Sub-1GHz ASK Modulation RF Receiver Module
DL-RXP4303 is a cost-efficient single chip wireless ASK receiving module, it is the most classic ASK receiving module in our Sub-1GHz RF Module products, mainly competed with the super-regenerative modules, with all the functions of high-end RF modules, and performs a very high receiving sensitivity. The sensitivity can reach -114 dBm under 3.3V @ 315MHz, which greatly increases the receiving distance.
At the same time, this model has a higher integration, with high frequency signal reception functionsall on chip.
Features
● Complete single chip UHF receiver with frequency range of 250-500 MHz
● Operating frequency: 433.92m, 315m (other frequencies can be customized)
● Receiving sensitivity at noise-free mode: - 96dbm (315MHz), - 96dbm (433MHz) - factory defaulted
● Receiving sensitivity at noise mode: -110dbm (315MHz), -110dbm (433MHz)
● Transmission rate: 10kbps (max), fixed automatic tuning
● No need for manual adjustment, and no external adjustable inductance/detector needed
● Working power: 2.7Ma (315MHz, full operation); 1μA (shutdown mode)
● Transmission distance: 300m in an open air (1200BPS)
● Working voltage: 2.4V-5.5V
● Independent 64 byte RXFIFO and TX FIFO
● Single serial port data transmission interface;
