20 MHz VHF CRYSTAL OSCILLATOR


Posted on Feb 6, 2014

A typical circuit at 20 MHz is shown. The crystal, which has an internal series resistance RS, of 14 ©, oscillates at its third harmonic. The diode clamp D1 and D2 provides a constant amplitude control. The transistor operates continuously in a linear mode over a complete cycle of oscillation, and reflects a reasonably constant load across the c
