<p>The resonator (Y) of the filter, or one of these resonators (Y3), is used, together with its input (BE) and output (BS) loops, as a balanced-output transformer. Thus the balanced output of the filter consists of the two ends (B12, B34) of the output loop of this resonator, and to which ends the mixer is directly connected. <IMAGE></p> |
