Wideband High Gain: Covers 10 kHz to 3 GHz, with up to 32 dB gain in the low-frequency band, meeting the needs of wide-band signal amplification. Adjustable Gain: Gain varies linearly with supply voltage from 5-8V. Automatic Gain Control (AGC) can be implemented via a DAC, simplifying circuit design. Low Noise and High Stability: Combines low noise figure with high stability when powered from 8-10V, making it suitable for sensitive receiver front ends. Extended lower frequency band: The default lower frequency band is 0.1MHz (with a 0.1μF), which can be extended to 5kHz by replacing the input and output capacitors (e.g., 10μF), meeting the needs of extremely low-frequency applications. Excellent gain flatness: Gain fluctuation is less than 1dB in the frequency band below 500MHz. Frequency Range: 10 kHz - 3 GHz (lower frequency adjustable via) Gain: Up to 32.5 dB at low frequencies (12V supply) Noise Figure: Low noise design, optimized for 8-10V supply Supply Voltage: 5-12V (gain adjustable with voltage) Gain Flatness:Less than 1 dB (Less than 500 MHz, after fine-tuning) Input/Output Impedance: 50Ω Features: Supports voltage-controlled gain, compatible with AGC applications Color: As Shown Material: PCB Package Contents: 1 x RF module 1 x Power supply line
