The merits of a doubly balanced mixer (DBM) include high dynamic range, good port-to-port isolation and rejection of even-order spurious responses. 1 The ring configuration, using two trifilar wound ferrite transformers, is most commonly used for DBMs at low frequencies. The application of a transformer DBM is, however, limited...
