<li>설명<br />
<ol><br />
<li>This product uses a voltage doubler detector (consisting of two reverse diodes.<br />
<li>1 time sensitive than single-tube detector(about 6dB), high sensitivity (typical -30dBm, or even to -40dBm) not ordinary 2AP9,1N60 can emulate.<br />
<li>input: 20dBm,<br />
<ol><br />
<li>Detection output: The default is positive<br />
<li>Working Frequency: 0.1-3200MHz<br />
<li>RC Filter: R = 10K, C = 1nF; (two elements in parallel output ports)<br />
<li>If you want to lower operating frequency, you can increase the of the output, if you want fast response, then need to reduce capacity, it is a contradiction that can be configured according to your needs.<br />

<li>30dBm = 7.071Vrms = 20Vpp<br />
<li>31dBm = 7.934Vrms = 22.437Vpp<br />
</ol><br />
</ol><br />
<li>고속 스위칭 회로가 아니므로, PIN diode를 사용할 필요가 없고, 낮은 전압을 통과시키는 schottky diode를 사용하는 것이 더 좋을 것임.<br />
