Patent ID: 7227419

Claim:
A power distribution network for an RF power amplifier, comprising: a first power distribution branch for distributing a power supply voltage to an input stage of a multistage amplifier circuit of an RF power amplifier; and a second power distribution branch for distributing said power supply voltage to an output stage of said amplifier circuit, wherein said first power distribution branch comprises: a first resistor having a first end configured to receive said power supply voltage, a first inductor having a first end coupled to said first amplifier stage and a second end coupled to a second end of said first resistor, a first capacitor having a first end configured to receive said power supply voltage and a second end coupled to ground, and a second capacitor having a first end coupled to the second end of said first resistor and a second end coupled to ground, and wherein said second power distribution branch comprises: a second resistor having a first end configured to receive said power supply voltage, a second inductor having a first end coupled to said second amplifier stage and a second end coupled to a second end of said second resistor, a third capacitor having a first end configured to receive said power supply voltage and a second end coupled to ground, and a fourth capacitor having a first end coupled to the second end of said second resistor and a second end coupled to ground.
