UHF 430MHz preamplifier Latest generation E-pHEMTThe preamplification module uses the latest technology on the market today offering very low noise characteristics and unmatched robustness.

UHF 430MHz preamplifier Low noise figure preamplifier with notch filter input for LTE frequencies. Unique in the world.

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.

 Field of use :

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.

Ultra Low Noise INNOVATIVE Preamplifier available for the 2 meter band. Low noise figure (type 0.35dB with coaxial relay active).

Thanks to the notch filter present at the input it is possible to attenuate the LTE frequency at 900MHz.

It can be powered, as well as by the passing capacitor, also through BIAS TEE with a voltage of 9 to 15V and a maximum absorption current of 130mA .
