20KHz - 3000MHz RF Wide Band LNA Low Noise Amplifier 32dB High Gain with SMA Female Connector
Description:
- This amplifier has the advantages of wide frequency range, high gain, and low noise figure, and can be used in various RF reception front-end to increase communication distance. Places that require low noise and small signal RF amplification, such as large-scale shortwave, FM broadcasting, remote control receivers, and cable TV signal amplifiers.
- The amplifier has high flatness in the band, especially in the operating bandwidth of 100KHz-500MHz, which has a superior flatness of less than 1dB.
Specification:
- Working frequency: 20KHz - 3000MHz
- Working voltage: 9 - 12V
- Working current: 27mA
- Amplification gain: 32dB (typ.)
F=0.1MHz, gain=32dB
F=500MHz, gain=32dB
F=1000MHz, gain=32dB
F=1500MHz, gain=32dB
F=2000MHz, gain=32dB
F=2500MHz, gain=30dB
F=3000MHz, gain=29dB
- Maximum output: 13dBm (20mW)
- System impedance: 50ohm
- Connector type: SMA-K
- Size: 25 x 33mm
- Weight: 5.9g
- Instruction:
RF in: input signal amplification
RF out: output amplification signal
VCC: positive power
GND: negative power
Application Skills:
- The frequency of the amplifier can also be changed by changing the input and output capacitance values to change the low-frequency bandwidth.
For example, by modifying the 1000NF capacitor, the low frequency can reach 100KHz;
By modifying the 1UF capacitor, the low frequency can reach 50KHz;
By modifying the 10UF capacitor, the low frequency can reach 1KHz.
- When the power supply varies between 8-10V, it can be used as a variable gain amplifier. The gain varies with voltage. As the voltage increases, the gain increases, while as the voltage decreases, the gain decreases.
- When the voltage is 9V, the amplifier output gain is 30dB and the noise figure is the smallest.
- The voltage of 12V can achieve a gain of 32dB.
Precaution:
- It is strictly prohibited to operate without load, and the power supply can only be carried out after the input and output are connected.
- The positive and negative poles of the DC when connected should be confirmed multiple times, reverse connection will cause module damage.
Package Included:
- 1 x LNA Module
