Zero-bias schottky power detector design for six-port based radar systems

This paper presents a zero-bias Schottky diode detector optimized for 24 GHz six-port radar applications. Based on a typical radar system, different requirements for the diode detector are derived. Moreover, a detector layout is chosen, a full mathematical model is presented and compared with Keysight ADS simulations. An optimization process is described to design a detector circuit which meets all specifications. As proof of concept a fabricated version of the circuit is characterized by measurement and the results are discussed.
