RF & microwave

Generate high-frequency clocks with our RF PLLs & synthesizers

Achieve ultra-low phase noise for high-performance test instrumentation, satellites, radar and 5G wireless systems

We offer a wide portfolio of RF phase-locked loops (PLLs) and synthesizers optimized for wideband, high-speed applications with synchronization and normalized phase noise less than –230 dBc/Hz. Our RF PLLs and synthesizers help reduce your design time while exceeding performance requirements for applications such as aerospace, defense, test and measurement, and wireless communications.

Low phase noise

Achieve the best phase-noise performance using our synthesizers with integrated voltage-controlled oscillators (VCOs) and PLLs

High-speed data converter clocking

Clock high-speed ADCs and DACs with SYSREF and JESD204B enabled devices

Space & high reliability

Operate in space and harsh environments with radiation-hardened and extended-temperature devices


Reduce current consumption for power sensitive and battery-operated applications
