Frequency Shift Keying (FSK)

FSK Receivers

Semtech’s wireless ultra-high frequency (UHF) radio frequency (RF) receiver products are designed to allow a minimum external component count, while maintaining RF design flexibility. Operating in license-free ISM bands, our UHF receivers comply with relevant European and North American standards. These ISM band RF receivers are unique, only consuming 3mA while in full active mode.

FSK Transceivers for Ultra Long-Range Communications

Semtech manufactures a wide range of RF transceivers for ultra long range, narrow-band and wide-band machine-to-machine (M2M) communications. These transceivers operate in the 433, 868 and 915MHz license-free ISM band. They showcase highly integrated RF transceiver chip architectures designed to maximize range, extend battery life, deliver robust performances, and minimize the use of external components.

FSK Transmitters

Offering a flexible low cost solution for an RF transmitter design, Semtech’s UHF transmitter requires extremely low power. Our devices are versatile, multi-channel ISM band RF transmitter IC chips that boast programmable frequency, data range and output power. These transmitters are well suited for cost reducing legacy products and for next-generation RF designs.

Our high-speed RF transmitters showcase high data communication rates of up to 600kbps and are compatible with European and North American regulations.
