ABSTRACT:
A detector module is described wherein the detector module includes a housing with a conductive waveguide, a detector, a temperature sensor, and detector circuitry. The waveguide is made of a conductive material and of an appropriate size for a signal of a particular frequency. The detector, which can be a detector diode, protrudes a distance into the waveguide so as to produce a detector signal. The temperature sensor generates a temperature signal responsive to a temperature. The detector circuitry is contained within the housing. Moreover, the detector circuitry is configured to receive and condition the detector signal into a detector module signal. The detector module signal and temperature signal are then associated with a previously calibrated power level. With calibrated power level information, an input signal to a transmitter can be attenuated or amplified to control its output power.
