1、A band-pass filter is a device that allows a particular frequency band to block other frequencies simultaneously 2、It is made of high quality metal, with sturdy structure 3、Many audio device of spectrum analyzer are using this circuit as a band-pass filter, to choose different frequency band signal, by the number of leds light up on the display indicates that the amplitude of the signal 4、In the circuit and electronic high frequency system, there is a good frequency filtering effect, and can suppress the signal and noise outside the band 5、High reliability, stable and reliable performance in full temperature range<div class="wang-edit-text"><span style="font-size:16px;font-family:Arial;"><strong>Descriptions:</strong></span> <span style="font-size:16px;"><span style="font-size:16px;"><span style="font-size:16px;font-family:Arial;">A band-pass filter is a device that allows a particular frequency band to block other frequencies simultaneously. </span><span style="font-size:16px;font-family:Arial;">In the circuit and electronic high frequency system, there is a good frequency filtering effect, and can suppress the signal and noise outside the band.</span></span></span> <span style="font-size:16px;"><span style="font-size:16px;"></span></span> <span style="font-size:16px;font-family:Arial;"><strong>Features:</strong></span> <span style="font-size:16px;"></span> <span style="font-size:16px;font-family:Arial;">A band-pass filter is a device that allows a particular frequency band to block other frequencies simultaneously.</span> <span style="font-size:16px;font-family:Arial;">It is made of high quality metal, with sturdy structure.</span> <span style="font-size:16px;font-family:Arial;">Many audio device of spectrum analyzer are using this circuit as a band-pass filter, to choose different frequency band signal, by the number of leds light up on the display indicates that the amplitude of the signal.</span> <span style="font-size:16px;font-family:Arial;">In the circuit and electronic high frequency system, there is a good frequency filtering effect, and can suppress the signal and noise outside the band.</span> <span style="font-size:16px;font-family:Arial;">High reliability, stable and reliable performance in full temperature range.</span> <span style="font-size:16px;"></span> <span style="font-size:16px;font-family:Arial;"><strong>Specifications:</strong></span> <span style="font-size:16px;font-family:Arial;">Input and output interface: SMA@50Ω</span><span style="font-size:16px;font-family:Arial;">Central frequency: 1090 MHz</span><span style="font-size:16px;font-family:Arial;">Pass band (3 dB bandwidth) : 14 MHz </span><span style="font-size:16px;"><span style="font-size:16px;font-family:Arial;">Insertion Loss </span><span style="font-size:16px;font-family:Arial;">: &lt;4dB</span></span><span style="font-size:16px;font-family:Arial;">Maximum load power: &lt;300mW (+25dBm)</span> <span style="font-size:16px;"><span style="font-size:16px;font-family:Arial;">Size:</span><span style="font-size:16px;font-family:Arial;">&nbsp;Approx. 4.5 x 3 x 1.2cm / 1.77 x 1.18 x 0.47inch</span></span> <span style="font-size:16px;font-family:Arial;">Weight: 37g</span> <span style="font-size:16px;"></span> <span style="font-size:16px;font-family:Arial;"><strong>Package Included:</strong></span> <span style="font-size:16px;"><span style="font-size:16px;font-family:Arial;">1 x </span><span style="font-size:16px;font-family:Arial;">band-pass filter</span></span> <span></span> <style> .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }</style></div>
