LNA 0.1-2000 MHz 60dB High Gain Low Noise Amplifier Board RF Broadband Module DC 6-12V 35mA Board

  Applications:The amplifier is based on the original 0.1--2000 + MHz (30dB) amplifier, using two-stage cascade is made with low noise, high gain (60dB), and is suitable to detect weak signals.Amplifier parameters indicators:Operating frequency: 0.2-1500MHzAmplifier Gain: 60dBMaximum output power: + 10dBm (10mW) @ 1dB compression pointWorking Current: 35mA (9V)Supply voltage: 6--12VDCSystem Impedance: 50 ohms The 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.
