The function of an Attenuator is to reduce the amplitude level without substantially distorting its waveform in the processing of a microwave signal. It contains a lossy element along the direction of the electromagnetic field vector, in order to disperse the energy. This article describes how to design a Digital Attenuator to convert a signal to a desired amplitude level via an electronic command.

The function of an I & Q Vector Modulator is to simultaneously control the phase and amplitude characteristics in the processing of a microwave signal. This device will convert a signal to a desired vector location via a digital command.

GT Microwave has amassed a wide product line of passive, analog and digital RF and Microwave Integrated Components. GT Microwave’s analog and digital phase shifters are an integration of either Varactor or PIN diodes with passive circuitry. They are continuously variable analog or converted to digital control or a true digital component that is switched from state to state. This application note applies to those components related to a desired change in the phase characteristics of a signal.
