專利摘要：
A radio frequency amplifier comprises a transistor, a transformer and a variable capacitor. The transistor has an input terminal, an output terminal and a control terminal. The transformer has a first coil conductor and a second coil conductor. The first coil conductor magnetically couples to the second coil conductor. The second coil conductor connects to the control terminal. The first coil conductor connects to the input terminal. The variable capacitor connects in parallel with the second coil conductor. An integrated circuit using the radio frequency amplifier is also introduced.
