— Herein, the paper presents RF front-end ICs for a wireless power transmission system (WPTS) employing phase conjugating retro-directive array. The system operates at 2.4 GHz ISM band. RF ICs includes a low noise small signal amplifier, mixer, and drive amplifier. RF ICs are implemented in Samsung 65nm RF CMOS technology. The size including all of the RF ICs is less than 4x4mm2. The supply voltage is 1.2 V. The circuit simulations are fully done with ADS and completely compatible with Cadence. The fabricated RF Front-end module is measured by a signal generator and a speed sampling oscilloscope. |
