Abstract: PURPOSE:To eliminate a fear to generate distortion or a clipping phenomenon in a voice even when a switching diode is nonconductive by connecting the serial circuit of a first diode, a second diode and a capacitor whose one edge is grounded to the serial junction of an inductance circuit. CONSTITUTION:To the serial junction between two inductance circuits L1 and L2, the serial circuit of a first diode D1, a second diode D2, and a capacitor C whose one edge is grounded is connected.

Title: High frequency power amplifier circuit
Inventor: FUKUDA TOSHIKAZU
IPC: H03F3/193
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To prevent electrostatic breakdown and to improve a frequency characteristic by providing a ground line through a transmission line between an input terminal and a matching circuit. SOLUTION: The ground line (short stub) 7 through the transmission line 8 is provided between the input terminal 5 and the matching circuit 11. Thus, static electricity flowing from the input terminal 5 is speedily discharged to the ground by providing the short stub 7 constituted of the transmission line 8. Since the transmission line 8 has high impedance in an operation frequency, the high frequency signal of the operation frequency, which flows from the input terminal 5, is supplied to the matching circuit without flowing into the ground through the short stub 7. Since the transmission line 8 generates resonance in the frequency twice as much as the operation frequency and it has low impedance, the signal of a second harmonic, which flows from the input terminal 5, flows out to the ground through the short stub 7 and it can be removed.
