Abstract
In this paper, we have developed the miniature ceramic PECL(positive emitter-coupled logic) VCXO of the $5{\times}7mm$ size for gratifying the requested specifications and the multilayer ceramic SMD(surface mounted device) package technology. The ceramic SMD PECL VCXO designed by the inverted Mesa type HFF is operating at the 3.3 Voltage and have the frequency range of 120MHz-180MHz. The Q factor is over 5K and it has the low jitter characteristics of 3.5 ps and low phase noise.
