Hybrid transistor

A transistor package having an operating range of frequencies, including:

• a body member;
• a plurality of metallized elements disposed on the body member in spaced relationship to one another and defining terminals including an input terminal, an output pad and a reference area;
• a transistor die disposed on the body member and defining a transistor and having at least one input electrode connected to the input terminal and at least one reference electrode connected to the reference area,
• the transistor die and the metallized elements being constructed and disposed relative to one another on the body member to define an equivalent output circuit having a capacitive reactance;
• first means disposed on the body member in contiguous but spaced relationship to the metallized elements to define a capacitance;
• and
• second means including a plurality of wires disposed on the body member and connected electrically to the first means and the metallized element defining the output pad to define an inductance in series with the capacitance,
• the first means and the second means being constructed to provide a resonance with the capacitive reactance in the equivalent output circuit at a particular frequency dependent upon the operating range of frequencies,
• the wires in the plurality being connected at one end to the first means and at the other end to the metallized element defining the output pad, the different wires in the plurality being distributed along such metallized element at their connections to such metallized element and being disposed in transverse relationship to one another.
