Design of a Novel Balun for a Star Configuration Double-balanced Mixer at S-band

A double-balanced mixer (DBM) has some advantages over other types of mixers. Ring and star configurations are available for the construction of a DBM. Between the two, the star configuration is preferred for high frequency operation. The star configur...
May 19, 2004
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...
