This RF broadband amplifier module is engineered for high-frequency applications, featuring a wide frequency coverage from 10kHz to 3GHz, up to 32dB gain, low noise characteristics, and medium-power output capability. The module enables dynamic gain adjustment through flexible supply voltage (5-12V), making it suitable for RF front-end reception, signal amplification, and automatic gain control (AGC) systems. It delivers stable performance with strong compatibility.
Frequency Range: 10KHz - 3GHz (lower limit adjustable via capacitor)
Gain: Up to 32.5dB at low frequencies (12V supply)
Noise Figure: Low-noise design, optimized at 8-10V supply
Supply Voltage: 5-12V (gain adjustable with voltage)
Gain Flatness: <1dB (<500MHz, finely tuned)
Input/Output Impedance: 50Ω
Special Features: Supports voltage-controlled gain, compatible with AGC applications
Communication Systems: RF front-end signal preamplification
Test Instruments: Auxiliary amplification for spectrum analyzers, signal generators
Research & Education: High-frequency circuit experiments and signal processing instruction
Industrial Control: Wireless Sensor Networks, Radio Frequency Identification (RFID) Systems
AGC Systems: Dynamic gain adjustment via DA control voltage
Bandwidth Extension: For operation at lower frequencies (e.g., 5kHz), replace input/output capacitors with 10μF and enhance power supply decoupling and regulation.
Gain Adjustment: Precisely control gain by adjusting the supply voltage within the 5-8V range. Pairing with a voltage regulator circuit is recommended to minimize fluctuations.
Performance Optimization: Lowest noise occurs at 8-10V supply, while maximum gain is achieved at 12V. Select the power supply scheme based on the application scenario.
Capacitance Calculation: When extending the lower frequency limit, calculate capacitance values based on 50Ω impedance to ensure complete signal transmission.
Warning: Never reverse DC polarity! Incorrect wiring will permanently damage the module!
Important: Always connect all input and output cables before powering on any module sold by this store! Never plug, unplug, or disconnect RF connections while powered!
Use low-noise LDO or regulated power modules to avoid introducing high-frequency ripple.
Ensure impedance matching and shielding during high-frequency layout to minimize radiated interference.
When replacing capacitors, select components with excellent high-frequency characteristics (e.g., NP0/C0G materials).
