Oscillators - (439 companies)

Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs.

Oscillator Type: XO | VCO | VCXO | TCXO
Package / Form Factor: Surface Mount Technology (SMT) | Through Hole Technology (THT) | Connectorized | Module / Board
RF Connector: SMA | Other
