| 摘要 |
<p>The digital radio frequency antenna system has an antenna (A) fed by a transmitter (32) with a preamplifier (33). A coupler (30) provides antenna connection and introduces a phase delay (42). A switch (43) in the coupling stage between a first transistor (36) source and earth provides switching between a transmitter broadcast and a blocked state.</p> |
