The broadband low noise amplifier adopts 2-level amplification, and the intermediate level reserves SAW filter positions. By default, it does not contain filters. Customers can DIY it by themselves. The chip operating frequency range is 50MHz to 3GHz, covering common frequency bands, the module is mainly used for regular operations such as weak signal amplitude enhancement and amplification, antenna gain compensation, etc. Frequency range: 50MHz to 3GHz System power consumption: DC/5v 42mA Module gain: 28dBm 1.5GHz,(42dBm 350MHz),(33dBm 1GHz) Chip P1dB:20dBm (select appropriate output signal strength according to actual needs) Interface Model: SMA-KFD46, feedthru capacitor is M3 3300pF Please note: There is a slight color difference or discrepancy in kind, it does not affect the use, please do not mind! Color: As shown Material: Metal Package Contents: 1 x Wideband Low Noise Amplifier Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
