               1. A transistor device, comprising: 
            a metal submount; 
                a transistor die arranged on said metal submount; 
                at least one integrated passive device (IPD) component comprising a substrate arranged on said metal submount; and 
                one or more interconnects extending between the transistor die and the at least one integrated passive device (IPD) component, 
                wherein the substrate of the at least one integrated passive device (IPD) component comprises a silicon carbide (SiC) substrate.
