High Impedance Amplifier-B

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 For Any Radio Receiver Radio SDR Intercom, etc., Malachite, Small Loop Antenna, for 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 the instability of the 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.

The specifications of the specific high-impedance amplifier are as follows:

1. Input impedance: 1Mohm
