The calibrator is a module that generates signals for the band 0.5 GHz to 18 GHz. These signals shall be generated by a Frequency Synthesizer and then amplified and equalized in the order to provide the same power at its 5 outputs. IN_CAL_1 and IN_CAL_2 inputs are for the band 0.5 GHz to 18 GHz and are used for internal calibration of the module. IN_CAL_1 shall be placed before equalization chain (equalizer, amplifier, variable attenuator), and the IN_CAL_2 shall be located after that. The logic control arrives to the calibrator as differential RS422.
The outputs provide the same power and the same group delay for any frequency and environmental condition. The output OUT_5 provides the same power as other outputs for any frequency and environmental condition. Also, the outputs OUT_1, OUT_2, OUT_3, OUT_4 and OUT_5 are be able to be attenuated by a variable attenuator.
