Product Description

Features:
-This product with wide frequency range, high gain, low noise figure
-This product can be applied to various rf receive front-end and increases communication distance
-Used for Short wave, FM radio, remote control receiver, such as cable TV signal amplifier need low noise rf signal amplification

Specifications:
Operating frequency0.1-2000MHz
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: 9-12 VDC
System impedance50

Tips:
1.When working frequency is less than 500 MHZit 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.

Package included:
1 * 0.1-2000MHz RF Wide Band Amplifier Module 30dB High Gain

4.0 out of 5 stars High gain amp - Works at 12V for full gain
Reviewed in the United States 🇺🇸 on December 14, 2020
This amplifier is good. It uses an old design or clone of INA-02186 and provides about 30..32dB of gain at 12V. The chip is biased with a 180 ohm resistor and pulls about 35mA of current. I measured about 10dB gain at 6V input the chip voltage was about 2V. I played with an adjustable power supply until i got a little over 5V on teh chip which was about 12V. At 9V the chip will not provide full gain/ power .
5.5V is well within specification for this chip. I use this amp for filter sorting. My jig for filter measurement has 32dB of attenuation and this brings the signal back to 0dB
I added a shield to avoid pickup from outside.
