The six-port network has been identified in recentyears as one of the best candidates to implement a SoftwareDefined Radio (SDR). The main characteristic of the six-portarchitecture is its extremely large bandwidth, which involvesmulti-band and multi-mode capabilities. However, broadbandsix-port network designs lead to large size circuits. Newtechnologies must be explored in order to achieve compact sizeand low-cost productions for configurable radio terminals. Inthis paper, the LTCC (Low Temperature Co-fired Ceramic)technology is proposed for implementing a six-port receiver. Inthe first place, we have developed a LTCC 90-degree hybridcoupler, which is the most critical component of the six-portnetwork. Measurement results show a good performance overthe frequency range from 1.5 to 6.5 GHz.
