Designed for a diverse range of consumer and industrial applications, the tiny LT series transceivers from Linx Technologies offer the long range and low power consumption. They operate in the 260 to 470 MHz band and are designed for full regulatory compliance and interference immunity. The modules operate over a 2.1 to 3.6VDC range and feature very low power consumption (7.6mA Tx, 6.1mA Rx, 11.5µA in sleep mode), a wide operational temperature range (-40 °C to +85 °C), adjustable transmitter power with up to +10 dBm output, and a typical receiver sensitivity in excess of –112 dBm.

Consequently the transceivers are capable of transparent serial data transfer at rates of up to 10 kbps over outdoor line-of-sight distances in excess of one mile. However, when the transmit power is set to the maximum allowed under FCC limits, that range will typically be reduced to 3,000 feet or less. Even applications not requiring long ranges will benefit from increased link reliability, said the manufacturer.

Data can originate from virtually any serial data source, including microcontrollers, RS-232, a Linx transcoder IC, or a Linx USB module. The modules are RoHS compliant and housed in a compact SMD package that is well suited to both prototyping and high-volume production. The transceiver can also be utilized with existing Linx LC and LR series transmitters and receivers, allowing for mixed mode and legacy configurations, as well as repeater capability for range extension. The LT series is available immediately at a cost of $9.80 in 10K production quantities.
