| We report the design and characterization of Schottky diode-based frequency triplers at W-band and 220-330 GHz band for the development of frequency multiplied signal sources to be used in a space-borne radar prototype for orbital debris detection and a 3-D imaging radar. The frequency triplers are designed with the aim of optimizing the bandwidth and conversion efficiency for a wide range of input powers, allowing the configuration of versatile sources able to fulfill the bandwidth and power requirements of diverse applications. Since self-heating is a significant limiting factor for the performance of high-power millimeter-wave frequency multipliers, the design procedure focuses on thermal management. A physics-based numerical self-consistent electro-thermal model is developed to optimize the Schottky diode electrical and geometrical parameters together with the multiplier circuit performance from a joint electrical and thermal point of view. For the purpose of improving the power handling capability, the multiplier circuit layouts are optimized via 3-D thermal modeling to maintain low operating temperatures. To complement the numerical approach, a physics-based analytical lectrothermal model is implemented into Keysight ADS to optimize the overall multiplier circuit performance accounting for the thermal effects. The incorporation of thermal aspects into the design procedure provides an integrated thermal management approach that allows optimizing the device and circuit performance and designing for reliability. | |
