frequency more easily converted for multiband operation. A common balanced modulator without balanced transformers, for ham use, is shown in Fig. 3. Notice that the matched diodes are connected in a ring rather than a bridge configuration. Good shielding procedures and matched components give a typical carrier attenuation of 40-45 dB.

It is not necessary to use four diodes to form a balanced modulator. As shown in Fig. 4, a two-diode balanced mixer in ring formation is also possible. However, the
