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.
