Features:100% brand new and high qualityThis RF Amplifier features low noise figure, is a LNA RF Amplifier.The amplifier is based on the original 0.1-2000 + MHz (30dB) amplifier, with a two-stage cascade, low noise, high gain (60dB)This Low Noise Amplifier is suitable for detecting weak signals.Application: LNA for the main mobile communication base station infrastructure applications, such as wireless communication transceiver card, tower mounted amplifier (TMA), combiner, Repeaters, and distal/digital wireless wide band end equipment application design.Specifications: LNA: 0.2-2000MHzAmplifier Gain: 60dBMaximum output power: + 10dBm (10mW) @ 1dB compression pointWorking Current: 35mA (9V)Supply voltage: 6--12VDCSystem Impedance: 50 ohmsWeight: Approx.8g/0.3ozThe amplifier uses some tips: 1) The amplifier at the operating frequency of less than 500MHz, has a very good gain flatness. The lower the frequency, the higher the gain consistency. 2) The lower limit of the operating frequency of the amplifier input and output capacitors are subject to default is 0.1uF, it can work to 0.2MHz; you can increase the input and output capacitors to extend the lower frequency limit. Applications should pay attention to enhance the power supply decoupling and regulator. 3) When the supply voltage 5-8V changes, can be used as a variable gain amplifier, the gain with the power supply voltage increases. DA control with the power supply voltage, you can control the amplifier gain, the gain adjustment. 4) When the supply voltage is 8-10V, low-end gain of 30dB, at which point the amplifier has a low noise figure and good stability. 5) When the voltage is 12V, maximum gain, low frequency gain up to 32.5dB, 6) Since the amplifier gain very high (60dB), the input attention overload (Fmax = -50dBm), in use should follow the relevant principles of RF and microwave circuit layout.Package list:1 x LNA RF Amplifier
