Latest generation E-pHEMTThe preamplification module uses the latest technology on the market today offering very low noise characteristics and unmatched robustness.
S21 of our preamplifier for 6 meters (50 - 54 MHz) with built-in VOX circuit. The notch filter action at 98MHz is clearly visible.
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.
Input 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.
Preamplifier with integrated VOX circuit, coaxile relays and bias tee on board. It can work up to 100W and performs TX to RX switching automatically.
