A system and method compensates for temperature in a signal path of an antenna array. The signal path includes an antenna element, a first phase shifter or a time delay unit, and a first variable gain power amplifier. The system and method can provide at least one of a local temperature signal, a remote temperature signal, and both the local temperature signal and the remote temperature signal to a slope control circuit, and provide a phase control signal or a gain control signal using the slope control circuit at least partially in response to the at least one of the local temperature signal, the remote temperature signal, and both the local temperature signal and the remote temperature signal.
