Abstract
The design of a 900 MHz ceramic oscillator, delivering a power of 10 dBm, has been carried out by using the negative-resistance condition. A new procedure based on the Nyquist criterion, implemented within microwave CADs has been used to test the onset of oscillations at the desired frequency and the presence of spurious oscillation. An excellent agreement between nonlinear simulations and measurements performed on a prototype has been observed.
