The NE688 series of NPN epitaxial silicon transistors are designed for low cost amplifier and oscillator applications. Low noise figures, high gain and high current capability equate to wide dynamic range and excellent linearity. NE688's low phase noise distortion and high fT make it an excellent choice for oscillator applications up to 5 GHz. The NE688 series is available in six different low cost plastic surface mount package styles, and in chip form.
