TE Connectivity Linx offers complete solutions to meet the requirements of many RC / RKE systems. The LR Series transmitter and receiver are low cost, high performance OOK radios. They are capable of over 2,500 feet of line-of-sight range. The LT Series transceiver is a combination of the LR Series transmitter and receiver in a package that is smaller than the receiver. It is suitable for the bidirectional transfer of digital data and is capable of over 3,000 feet of line-of-sight range. The KH3 series combines a transmitter and low security encoder as well as a receiver and low security decoder. The TT Series and RC Series are products that combine a transceiver and medium security transcoder into a single part. They use a Frequency Hopping Spread Spectrum algorithm to meet the legal requirements for higher output power and to make the system more immune to noise. Other modules are available for FM modulation and transmission of data and analog information such as audio.
