In this work we present the design of a 400 GHz Schottky diode mixer for high performance operation. In order to achieve a proper design a full and joint optiinization of both the external circuit and the internal structure of the Schottky diode is performed. Two possible mixer topologies are analyzed: A fundamental mixer and a subharmonically-pumped (SHP) ant parallel diode pair mixer. The advantages and disadvantages of both topologies are discussed. The final results exhibit a single-side band (SSB) conversion loss of 8.6 dB t 0A mW of LO power for the 400 GHz fundamental mixer and 103 dB 0.8 TriW Lo power for the 400 GHz SLIP mixer, when parasitics are tuned out However, if parasitics are not tuned out, an increase in the required LO power is necessary for minimum conversion loss.
