RF CIRCUITS DESIGN BASICSRF circuit design: Basics Akira Matsuzawa Tokyo Institute of Technology 1 Contents Building blocks in RF system and basic performances Device characteristics in RF application Low noise amplifier design Mixer design Oscillator design 2 Basic RF circuit block RF systems are composed of limited circuits blocks. LNA, Mixer, and Oscillator will be discussed in my talk. Receiver 1) Low Impedance Noise Matching Amp. 2) Mixer Filter Transmitter Power Amp. 3) Oscillator 3 Basic functions of RF building blocks Amplifier, frequency converter (mixer +oscillator), and filer are basic function blocks in RF system. 2) Mixer+ Oscillator Undesired Down conversion dB 3) Filter Frequency conversion dB Desired 1) Amplifier Log (f) Up conversion Log (f) 4 RF Amplifier Gain: Amplify sm……
