<p>The present invention is an oscillating apparatus and a method for Time Division Duplex (TDD) in a wireless communication system. In a Phase-Locked Loop (PLL) synthesizer applied to the wireless communication system, an oscillation signal generating from a PLL circuit is output by way of an isolation unit in which a capacitor for Direct Current (DC) blocking and a predetermined isolator are combined to form one body. Hence, the oscillation signal isolated from a subsequent circuit through the isolation unit is not affected by the effect of switching noises that flow from a Radio Frequency (RF) switch or into a power amplifier of a transmitter during switching between each Down Link (DL) frame and each Up Link (UL) frame, and therefore the performance of a system can be improved.</p> |
