Oscillator with a low power consumption

An oscillator, comprising:

• a package module including
• a cover, and
• a base that is attached to said cover, and that cooperates with said cover to define an airtight space therebetween;
• a circuit module disposed in said airtight space in said package module, and including
• a dielectric substrate,
• a crystal resonator that is mounted on said dielectric substrate and that is operable at a resonant frequency, and
• a heating controller circuit that is mounted on said dielectric substrate, and that is operable so as to generate heat in order to maintain said airtight space in said package module at an operating temperature;
• a plurality of conductive pins, each of which extends into said airtight space in said package module through said base of said package module;
• and
• a plurality of conductive arms disposed in said airtight space in said package module, each of said conductive arms having a first end that is connected to said dielectric substrate and said crystal resonator of said circuit module, a second end that is connected to a respective one of said conductive pins, and an intermediate portion that extends between said first and second ends thereof and that has a length longer than the shortest distance between said first and second ends thereof.
