Product detailed description

TEROZ 604X antenna amplifier, low noise, DAB, G23dB, F0,7dB, U>120dBµV, F-F
The Teroz 604X amplifier for the VHF (DAB) band 174 to 240 MHz is equipped with a miniature microwave amplifier with E-PHEMT (ultra low noise) technology. At the input and output of the amplifier are circuits that suppress unwanted signals outside the operating band and adjust the impedance to 75Ω unbalanced. Practical tests have shown that the amplifier is capable of handling an antenna signal with a level of around 30dBµV, which is at the noise floor and thus suitable for long-distance reception. This amplifier is of great use in places where there is a very weak useful signal in close proximity to a strong interfering signal, where the signal from the antenna must first be amplified and only then can the interference be detuned. The high build-up capability of this amplifier allows just such use without the danger of waking up a strong signal and degrading the useful signal. In this case, it is recommended to place the amplifier as close as possible to the antenna, since every dB of attenuation of the coaxial cable is added to the noise of the amplifier. The amplifier can significantly reduce the noise figure of the entire amplifier chain in this frequency band.
However, the amplifier is also suitable as a power element for larger signal distribution systems, as it is able to deliver an undistorted signal with an output level exceeding 120 dBµV!!!! Which is comparable to the values of power amplifiers for STA and TKR, but at an incomparably lower price.
