Abstract
A heater apparatus (10) for a piezoelectric device (12) includes a resistive heating element (18) on an insulating substrate (14). The heating element (18) maintains a temperature of the piezoelectric device (12) within a predetermined temperature range. A plurality of electrical couplings (20) extend through the insulating substrate (14). The electrical couplings (20) electrically connect to the heating element (18) and mechanically and electrically connect to the piezoelectric device (12). The piezoelectric device (12) is suspended above the heating element (18) on at least two of the electrical couplings (20). As a result, the heater apparatus (10) and piezoelectric device (12) can be enclosed within a standard crystal package.
