CMOSTEK
RF ICs, sub-GHz transceivers and digital interface isolators
About the manufacturer
CMOSTEK is a semiconductor brand specializing in wireless RF devices and low-power mixed-signal solutions. The company develops the NextGenRF family of transmitters, receivers and transceivers for sub-GHz wireless systems.
CMOSTEK RF devices support common OOK and (G)FSK modulation schemes and are designed to reduce external component count and power consumption. They are well suited to battery-powered devices, telemetry, remote controls, alarms, wireless sensors and IoT systems.
The portfolio also includes interface devices such as digital isolators. These components provide galvanic separation between system domains, protect control logic and improve immunity to ground potential differences and electrical noise.
Applications
CMOSTEK components are intended for systems that require low power consumption, straightforward sub-GHz radio implementation or reliable isolation of digital interfaces.
- IoT and telemetry – sub-GHz wireless data transmission.
- Alarm systems – wireless sensors, remote controls and signaling devices.
- Building automation – communication between distributed control modules.
- Battery-powered equipment – applications requiring very low energy consumption.
- Industrial automation – isolation between different sections of a control system.
- I2C interfaces – galvanic isolation of digital buses.
- Remote control – OOK/FSK transmitters and receivers.
