A high directivity quarter-wave microstrip coupler with a cancellation circuit of a Wilkinson divider is presented. The presented coupler utilizes a cancellation circuit between a coupling port and an isolation port of the conventional quarter-wave microstrip coupler to enhance the isolation at the desired frequency. The cancellation circuit consists of the Wilkinson divider, and an attenuator. The...
New optical coupling technology with flexible printed circuit has been developed for PLC-based Triplexer. This technology realizes high PD coupling performance even small detecting area. It is suitable for cost reduction and high productivity.
