This paper presents a new compact 90deg hybrid coupler using multi-layer technology. In order to reduce an intrinsic circuit area of the hybrid coupler, a compact meandered line configuration and a new multi-layer structure design have been adopted. The configuration and structural dimensions of the multi-layer structure were designed and investigated through detailed 3-D electro-magnetic simulations. The measured insertion loss is less than 0.4 dB, and the phase imbalance is less than 3 degree with the frequency range from 380 MHz to 520 MHz. The overall dimension is as small as 16.5 mm times 12.2 mm times 1.66 mm. |
