Disclosed is a no power hybrid integrated circuit (IC) for wireless communication for radio frequency (RF) emission monitoring, installed on an RF transmission path, including a directional coupler and an RF detection circuit unit. The directional coupler is installed between an RF input end and an RF output end, to be reachable through signals, thereby outputting RF signals, received by the RF input end, into both a first path and a second path separately, wherein the first path is configured to output the RF signlas towards the RF output end and the second path is different from the first path. The RF detection circuit unit converts the RF signals, received through the second path divaricated from the directional coupler, into voltage by using a diode and capacitor and operates LEDs using the converted voltage. Therefore, by using the present invention, whether RF signals are emitted normally or not can be checked intuitively and constantly through LEDs even without separate external power.
