High Impedance Amplifier, Professional Hi Z Amplifier for Donut Antenna and Software Radio Loop Antenna, Built-in 600Mah Li-ion Battery

High Impedance: Because the impedance generated by LC resonance is very high, this amplifier can be directly connected to an LC resonant antenna to directly extract energy from the resonant antenna, achieving higher gain and frequency selectivity. LC resonant antennas include donut antennas and magnetic bar antennas. Applications: The high-resistance amplifier is an impedance conversion device that converts high impedance to a standard 50-ohm output impedance, performing impedance matching and isolation. It is primarily used for receiving matching of passive antennas and is suitable for donut resonant antennas, tie rod antennas, whip antennas, and magnetic rod antennas. Improved Performance: A higher input impedance allows as much energy as possible to be extracted from the input antenna, reducing signal energy loss caused by the unstable impedance of the input antenna and significantly improving receiving performance. Parameters: The high-resistance amplifier has an input impedance of 1MΩ, an output impedance of 50Ω, a gain of 0dB, a bandwidth of 300MHz, and a built-in 600mAh lithium-ion battery for extended use. Compatible: Can be used with any wireless receiver radio such as software defined radio, malachite, small loop antenna, donut antenna, mini loop, radio antenna, tuning loop and other models.
