| Abstract(in English) | As functions of a communication device are multiplying these days, the device with multiple circuits, such as RF, digital and switching power supply, are increasing. For the multiple functions device, harmonic responses of digital clock signals and switching power supplies are becoming problems as internal electromagnetic noises into RF circuits. In this report, we focused on an RF amplifier as one of the circuits suffering the problem, and evaluated its immunity characteristics for power supply terminals by measuring "immunity level", which is defined as voltage ratio of input and output noises. From the measurements, "immunity level" for the power supply terminals of the RF amplifier was evaluable and found to be insensitive to voltage level of the input noise. Moreover, it was cleared that "immunity level" decreases as output level increases. |
