FET BALANCED MODULATOR FOR SSB


Posted on Feb 6, 2014

AF modulating signal is applied to gates of matched FETs in push-pull through T1 having accurately center-tapped secondary, and RF carrier is applied to sources in parallel through C3. Carrier is canceled in output circuit, leaving two sidebands. R3 is adjusted to correct for un-balance in circuit components. -R. P. Turner, `FET Circuits, ` Howard W
