Advantages of using Quadrature Digital Upconverters (QDUC) in point-to-point microwave transmission systems (PDF with circuit diagram!)

Crystal oscillator 2.5*2.0mm 2520 0.67M~170M OSC can be supplied at any frequency

RF cable can be customized for other specifications

Introduction:

Wireless systems typically use direct conversion and superheterodyne transmitter architectures. This application note briefly reviews the pros and cons of the various approaches (see the "References" section for additional resources) and provides an architectural choice (direct real IF) that is ideal for use in microwave point-to-point radio indoor units (IDU). ) The generation of IF.
