Apparatus for degrading Q in a high-Q RF pulse transmitting system and the like

摘要

A high-Q, pulse transmitting antenna system is disclosed, as of the Loran type, wherein a simple solidstate circuit, employing mainly passive elements serves, during quiescent periods between transmissions, to introduce loss into the antenna circuit, thereby selectively to lower the Q of the antenna circuit and thus prevent spurious oscillations therein during such quiescent periods.
