High frequency signal switching device |
摘要 |
An improved high frequency signal changeover switch is provided for use especially as a horizontal-vertical selection switch in an artificial satellite broadcast receiving system for the purpose of selectively delivering either vertical or horizontal polarization signals received at its two inputs, respectively, from its single output. This inventive switch has such a significant feature over the prior art switches in that no mismatch occurs among all of these terminals.
