In May 2012, Semtech Corporation launched a fully integrated, low cost amplitude shift keying or on-off keying radio transmitter called the SX1243.

Features and USP: The SX1243 is a fully integrated, low cost FSK/OOK radio transmitter designed to replace surface acoustic wave (SAW) based resonator transmitters in garage door openers, remote keyless entry (RKE) devices and other consumer remote control systems. The SX1243 features a fractional-N phase lock loop (PLL), which delivers higher performance and more flexibility, while minimising the BOM cost versus traditional SAW-based resonator designs. The transmitter covers the frequency bands from 310 MHz to 450 MHz, 860 MHz to 870 MHz, as well as 902 MHz to 928 MHz, which makes it suitable for worldwide operation and regulatory compliance.
