Features: 100% brand new and high quality Specifications Size：25*52mm Diameter of end: 5mm Color：green + gold Operating frequency：0.1-2000MHz Amplifier gain： F=0.1MHz, gain=32dB F=500Mhz, gain=31dB      F=1000MHz, gain=29dB F=1500Mhz, gain=25dB F=2000MHz, gain=20dB Maximum power output：+10dBm （10mW） Power supply voltage: 6-12 VDC System impedance：50Ω Tips： 1.When working frequency is less than 600 MHZ，it get well gain flatness, can make it less than 1dB after careful adjustment. The lower frequency the higher gain consistency. 2.Amplifier working frequency of the lower limit is subject to input and output capacitor, the default value is 0.1 uF, working to 0.1 MHz. Increase the input and output capacitance appropriately,can extend the cut-off frequency, such as 10uF capacitance can work to 5KHz. 3.When the power supply voltage changes in 5-8 v, it can be used as a variable gain amplifier, gain increases with the increase of the power supply voltage, which suitable for radio frequency receive front-end circuit, using DA control power supply voltage, to control the gain of the amplifier, automatic gain control 4.When the power supply voltage in the 8-10 v, the low frequency end gain up to 30 db, at this time the amplifier has a low noise coefficient and good stability. 5.When the voltage is 12 v, reach maximum gain, the low frequency end gain of 32.5 dB Note: 1.Due to the hand measurement, there have size error about 1-3cm 2.Please be reminded that due to lighting effects and monitor's brightness/contrast settings etc, the color tone of the photo and the actual item could be slightly different Package included 1x wide-band amplifier         Le 19-janv.-20 à 00:22:39 Paris, le vendeur a ajouté les informations suivantes:
