High Impedance Amplifiers Suitable For Walkie-Talkie Small Loop Antenna

feature: *The high-impedance amplifiers is an impedance conversion device that can convert higher impedance into a standard 50-ohm output impedance thereby playing the role of impedance matching and isolation. *High-impedance amplifiers are mainly used for passive antenna receiving matching suitable for sweeteners. Donut Resonant Antenna Whip Antenna Whip Antenna Whip Antenna etc. *High Impedance amplifiers for use with any radio receiver radio walkie-talkie etc. Malachite Small Loop Antenna Donut Antenna Mini Loop Radio Antenna Tuning Loop. (And other models) The higher input impedance can get as much energy as possible from the input antenna reduce the signal energy loss caused by the unstable input antenna impedance and greatly improve the receiving performance. *Since the impedance generated by the LC resonance is also high this amplifiers can be directly connected to the LC resonant antenna to obtain energy directly from the resonant antenna for higher gain and frequency selective characteristics. *LC resonant antennas include loop antennas. Magnetic rod antenna etc. Specification: The specifications of the specific high-impedance amplifiers are as follows: 1. Input impedance: 1MΩ 2. Output impedance: 50Ω 3. Gain: 0dB 4. Bandwidth: 300MHz 5. Charging voltage: 5V 6. Built-in battery capacity: 800mAH 7. Charging current: 600mA 8. Working hours: >24h 9.
