Abstract
In this letter, a feedforward embedding technique is presented to impr ove the isolation of a circulator. The circuit configuration is partic ularly suitable for transmit/receive applications where the received s ignal is extremely weak compared to the transmitted signal and where a mismatch at the antenna may exist. It is demonstrated that the isolat ion of a circulator can be improved by an additional 30 dB by using a feedforward embedding method. Test performance of a commercial 1-GHz c irculator with and without the feedforward network is shown.
