Abstract: An apparatus including a circuit, a temperature sensor, a sensor and a control system. The circuit may be configured to receive an input signal and a configuration signal and generate an output signal in response to performing an upconversion of the input signal to a selected frequency band and an amplification of the input signal in response to the configuration signal. The temperature sensor may be configured to measure a temperature. The sensor may be configured to measure a sensor value. The control system may be configured to generate the configuration signal in response to the temperature and the sensor value. The configuration signal may be generated to maintain a gain of the amplification at a target level over a range of an operating condition during the upconversion. The target level of the gain for the operating condition may be determined in response to a pre-determined calculation.

Abstract: An apparatus comprising a frequency standard circuit and a tracking circuit. The frequency standard circuit may be configured to generate an internal frequency standard and adjust the internal frequency standard in response to a tuning signal.

The tracking circuit may have a bandwidth that prevents unwanted content on the reference signal from corrupting the internal frequency standard.
