CA 2274335

An oscillator module in which external wires can be reduced, and characteristics of a resonator and oscillation margin can be measured. A circuit portion for oscillation and a two-port surface acoustic wave resonator are sealed in a package, one of the terminals of the two-port surface acoustic wave resonator is connected inside the package to an input terminal of the circuit portion for oscillation. The number of external terminals provided to the package can be reduced, enabling the oscillator module to be made small-scale and at lower cost. Furthermore, it is possible to measure the insertion loss and resonant frequency of the two-port surface acoustic wave resonator, and the oscillation margin of the oscillator module, making it possible to improve the yield of the oscillator and reduce costs.
