ABSTRACT:
In an interface circuit for connection to an output of a frequency converter, at least two current paths are coupled to one another in parallel. Each current path includes at least one cascode stage for signal processing. The circuit compensates for DC voltage offsets of the frequency converter, and has a gain ratio that can be changed over for signals with a large dynamic range.
