0.1-2000mhz RF Wideband Amplifier Gain 30db Low-Noise Amplifier LNA Board Module

The 0.1-2000MHz RF Wideband Amplifier with a gain of 30dB, Low-Noise Amplifier (LNA) Board Module, is designed for various RF receive front-end applications to enhance communication distances. This module finds widespread utility in Shortwave, FM radio, and remote-control receivers, particularly for cable TV signal amplification requiring low-noise RF signal enhancement.

Operating Tips:

1. The lower limit of the amplifier’s working frequency is determined by the input and output capacitors, with a default value of 0.1uF, functioning down to 0.1 MHz.

2. Adjusting the input and output capacitance appropriately can extend the cut-off frequency. For example, a 10uF capacitance allows operation down to 5KHz.

3. For power supply voltages ranging from 5V to 8V, the amplifier can function as a variable gain amplifier. Gain increases with higher power supply voltage, making it suitable for radio frequency receive front-end circuits. Using digital-to-analog (DA) control of the power supply voltage allows for gain control, enabling automatic gain adjustment.

4. With a power supply voltage between 8V and 10V, the low-frequency end gain can reach up to 30 dB, offering a low noise coefficient and good stability during this operational range.

5. At a voltage of 12V, the amplifier reaches its maximum gain, with the low-frequency end gain reaching 32.5 dB. This configuration ensures optimal performance under these specific voltage conditions.
