The modulation provided by IC u1. The modulation provided by IC u1. The output of U1 has the matching network consisting C2, L1, L2 that limit the harmonic content and affect the proper coupling of the antenna to the output stage. Antenna, Ground and Power Source: The antenna consists of PCB antenna with 0.0dBi gain. The ground is only that of the printed circuit board. Electric current is supplied by 3.7V rechargeable battery. Operation Descriptions: The Equipment Under Test (EUT) is a mobile 2.4GHz transmitter, The transmitter is light control system. The transmission signal is frequency hopping with channel frequency range 2403.0- 2480.0MHz during normal use. The EUT was set to fixed frequency test mode by application. The EUT is powered by 3.7V rechargeable. After switching on the EUT, the light can be controlled by remote. The …
