rele coassiale preamplificatore 50 MHz True miniaturized coaxial relaysThe relays used in all our preamps are coaxial and non-traditional. In our circuits AXICOM HF-3-56 are used which allow an isolation between the ports of over 80dB, an insertion loss of only 0.03dB and an excellent return loss.
filtro notch ingresso preamplificatoriInput notch filterOur pole and coaxial preamps for 50 MHz are the only ones on the market to have a 88-108MHz notch filter. This solution helps to amplify only the signals and not overloading the radio frontend.
Support Bias TeeAll our preamps are also powered by coaxial cable. A bias tee must be purchased.
Output band pass filterEach preamplifier has a band-pass filter at its output to further help the front end of your radio not intermodular.
