The low noise amplifier module has a higher gain and provides very low noise over a wide frequency range. This provides communication between the receiver and the transmitter. The amplifier operates from a single +5V supply. It has very good stability, and has a wide dynamic range and a wide operating frequency range. It is suitable for fixed gain amplification of signals. Technical indicators: 1) Operating frequency: 50-4000MHz 2) Amplification gain: 21.8dB (typical) 3) Noise figure: 1.3dB (typical) 4) Maximum power: +22dBm (150mW) @1dB compression point 5) Working current: 125mA (5V) 6) Power supply voltage: 5VDC 7) System impedance: 50 ohms Color: As shown Material: Electronic Component Specification: Package Contents: Package included: 1 x 50-4000MHz Low Noise Amplifier TQP3M9009 LNA Module Only the above package content, other products are not included.
