摘要： 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.

摘要： Various embodiments provide for systems and methods for increased linear output power of a transmitter. An exemplary wireless communications system for transmitting an input signal comprises a predistorter module, a GaN power amplifier, a coupler, and an antenna. The predistorter module is configured to detect existing distortion by comparing the input signal to a feedback signal and generate a correction signal. The predistorter may adaptively adjust its operation to minimize the existing distortion due to GaN power amplifier nonlinear characteristics. The result is that the GaN power amplifier may send a power signal of improved linearity to the antenna. The coupler is configured to sample the amplified signal from the GaN power amplifier to generate the feedback signal. The antenna is configured to transmit the amplified signal.
