The broadband low noise amplifier adopts 2level 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 3GHzSystem power consumption: DC/5v 42mAModule gain: 28dBm 1.5GHz,(42dBm 350MHz),(33dBm 1GHz)Chip P1dB:20dBm (select appropriate output signal strength according to actual needs)Interface Model: SMAKFD46, feedthru capacitor is M3 3300pFPlease note: There is a slight color difference or discrepancy in kind, it does not affect the use, please do not mind!Color: As shownMaterial: MetalPackage Contents:1 x Wideband Low Noise AmplifierOnly 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.
