High Impedance Amplifier for SDR Walkie Talkie Small Loop Antenna Donut Antenna High Impedance Amplifier for SDR Walkie Talkie Small Loop Antenna HackRF One Donut Antenna Product Description: High-impedance amplifier is an impedance conversion device, which can convert higher impedance into standard 50 ohm output impedance, so as to play the role of impedance matching and isolation. High-impedance amplifier is mainly used for passive antenna receiving matching, suitable for sweet Donut Resonant Antenna, Whip Antenna, Whip Antenna, Magnetic Rod Antenna, etc. High-impedance amplifier, can be used in any radio receiver, radio SDR walkie-talkie, etc., Malachite, Small Loop Antenna, HackRF One, Donut antenna, Mini Loop, Radio Antenna , the tuning ring. And other models) higher input impedance can get as much energy from the input antenna as possible, reduce the signal energy loss caused by unstable input antenna impedance, and greatly improve the receiving performance. Since the impedance generated by the LC resonance is also very high, this amplifier can be directly connected to the LC resonant antenna to obtain energy directly from the resonant antenna, which can obtain higher gain and frequency selection characteristics. The LC resonant antenna includes the donut antenna. Magnetic Rod Antenna, etc. Specifications: 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. Size 50x45x18mm Package Included: High impedance amplifier*1
