Abstract:
An internally impedance matched transistor circuit comprising, in a single package:at least two internally matched transistor circuit units, each transistor circuit unit including:a semiconductor element for signal processing a high frequency signal;an input impedance matching unit having an input impedance matching circuit for impedance matching between said semiconductor element and an input terminal to which a high frequency signal is applied from an external source;an output impedance matching unit having an output impedance matching circuit for impedance matching between said semiconductor element and an output terminal from which is output a high frequency signal processed by said semiconductor element; andan oscillation preventing stabilization circuit unit having an oscillation preventing stabilization circuit comprising a resistor and a capacitor connected in a series circuit, the resistor being connected to ground through the capacitor and to an input of the semiconductor element, wherein the internally matched transistor circuit units are connected in parallel with the input terminals connected together and the output terminals connected together.
