High Impedance Amplifier Suitable for SDR Walkie Talkie Smal

Detailed Information About The Product:

High impedance amplifier is an impedance conversion device that can convert high impedance to standard 50 ohm output impedance, thereby achieving impedance matching and isolation.
High impedance amplifier is mainly used for passive antenna reception matching, suitable for donut resonant antennas, telescopic antennas, whip antennas, magnet antenna and other types.
High impedance amplifier can be used in any radio receivers, radio SDR intercoms, malachite, small loop antennas, for HackRF One, Donut antenna, Mini Loop, radio antenna, tuning loop. The higher input impedance of the device (such as the Sony α7 and Sony α7R) can capture as much energy as possible from the input antenna, reducing signal energy loss caused by unstable input antenna impedance, which can greatly enhance reception performance.
Due to the high impedance generated by LC resonance, this amplifier can be directly connected to an LC resonant antenna, which can directly harvest energy from the resonant antenna, resulting in high gain and frequency selective characteristics. LC resonant antennas include doughnut antennas and magneto-rod antennas.
