RF433 MHz Transmitter Receiver Wireless Module

RF433 MHz Transmitter Receiver Wireless Module

This 433 MHz wireless RF module is a superheterodyne ASK (Amplitude Shift keying ) / OOK (On-Off keying based ) module. The design idea is to use a SAW filter, highly suitable for industry control or bad place for use, with strong anti-jamming. Built-in automatic gain circuit (AGC), will automatically change front-end LNA gain among received signal strength also make signal output not be strong or weak signals caused by phase distortion so that it can rise higher sensitivity.

To receive the local oscillation circuit for the PLL lock loop design, no offset, and stability is high. The frequency is 433MHz and the receiver structure is Superheterodyne, the received signal is OOK. After receiving the signal, it will output the TTL signal to the external decoder IC for decoding. It is convenient to the applicant in different products and external components are not necessary to make products wireless and also bring value-added for your products.
