Description:
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: 0.2-1500MHz
Amplifier Gain: 60dB
Maximum output power: + 10dBm (10mW) @ 1dB compression point
Working Current: 35mA (9V)
Supply voltage: 6--12VDC
System Impedance: 50 ohms
The amplifier uses 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.
