ABSTRACT:
A high frequency switch includes electrically connected switching elements, such as a first diode, a second diode, inductors, capacitors, and a resistor. A diode having a smaller charge capacity in the ON state is used as the first diode, while a diode having a larger charge capacity in the ON state is used as the second diode. That is, the first and second diodes utilize different part number diodes. A diode part number having a smaller charge capacity is used as the first diode, while a diode part number having a larger charge capacity is used as the second diode. Alternatively, the charge capacity of diodes that belong to the same lot may be measured and classified, so that a smaller charge capacity diode is used as the first diode, while a larger charge capacity diode is used as the second diode.
