Problems solved by technology
However, there is no guarantee of perfect matching of temperature coefficients of materials and components and perfect assembly at manufacture to match their behavior to temperature fluctuations
In addition, existing technologies involving careful selection of critical components such as VCOs limit the number of vendors with proprietary technology and product quality
Also, even with specially selected components, thermal testing can lead to low manufacturing yields due to component defects
Therefore, thermal testing must be repeated several times, which increases product cost

A frequency synthesizer module with phase hits compensation, comprises an enclosure; a frequency synthesizer within the enclosure; and a heater module including a heater element in thermal communication with the frequency synthesizer for producing heat to adaptively adjust frequency synthesizer temperature. The frequency synthesizer module may be in an ODU and electrically isolated from the heater module. The heater module may include a posistor that varies based on temperature; and a voltage regulator having an input pin for receiving a varying input voltage, an output pin for providing a modifiable output voltage to the heater element for adaptively adjusting the heat generated thereby, and an adjust pin coupled to the posistor for maintaining a substantially constant voltage at the adjust pin. The heater module may heat when below room temperature, heat at less than maximum power when between room temperature and a threshold, and deactivate when above the threshold.
