Robostall 434 mhz wireless rf module is a superheterodyne ask (amplitude shift keying ) / ook (on-off keying based ) module. Design ideal is to use saw filter, highly suitable for industry control or bad place for use, strong anti-jamming. Built-in automatic gain circuit (agc), it will automatically change front-end lna gain among received signal strength also makes signal output will not be strong or weak signals which 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. Frequency is 433. 92Mhz and receiver structure is superheterodyne, received signal is ook. After receiving signal, it will output ttl signal to external decoder ic for decoding. It is convenient to applicant in different products and external components are not necessary to make products be wireless also bring value-added for your products.
Operating current 5 ma
Receiver sensitivity as high as -110dbm –
