Field of use :
- Preamplifier made with 4-layer pcb with integrated VOX circuit, coaxial relays and integrated bias tee. It can work up to 100W and switches from TX to RX automatically. INNOVATIVE Ultra Low Noise UHF preamplifier available for the 70 cm band operating with a low noise figure (typ. 0.80dB with active coaxial relay) from 420 to 450 MHz. Thanks to the notch filter present at the input it is possible to attenuate the annoying LTE frequencies at 900MHz with an attenuation of about 40 dB. Made in our cylindrical anticorodal aluminum structure. It can be powered, as well as by the passing capacitor, also by BIAS TEE with a voltage from 9 to 15V and a maximum absorption current of 137mA.
