architecture delivers outstanding stability and frequency accuracy, while
minimizing the effects of antenna port loading and mismatching. This
reduces or eliminates frequency pulling, bit contraction, and other negative
effects that are common to SAW-based transmitter architectures, providing
a significantly higher level of performance and reliability.
When a button is pressed on the transmitter, power is applied to the

internal circuitry and the encoder IC is enabled. The encoder detects the
logic states of the address lines and button data lines. These states are
formatted into a three-word transmission cycle that continues until the
button is released. The encoder data is used to modulate the transmitter,
which, through the antenna, conveys the data into free space. On the
receiver side, a decoder IC or custom microcontroller is used to check
the transmitter’s address bits against the address settings of the receiving

The transmitter is compatible with several Linx receiver products, including
the LR, KH2, KH3, LT and OEM product families. For applications where
range is critical, the LR Series receiver is the best choice due to its
outstanding sensitivity. When the transmitter is combined with an LR Series
receiver and the DS Series decoder, ranges of up to 1,000 feet (300m) are

from the increased link reliability and superior noise immunity provided by
the LR Series receiver.
