Abstract :
In this paper, a tri-port attenuator is proposed for the test system of wireless keyboards. The attenuation performance is achieved by using the couplers´ isolating function ingeniously. The proposed attenuator can help to reduce crosstalk among the test systems and makes the systems have good uniformity. For the requirements of test system, the tri-port attenuator is designed and realized with -30dB attenuation at center frequency 2.45GHz. And its coupling coefficient is designed among -3~ -4dB for testers to monitor the received signal of the system conveniently.
