INNOVATIVE miniaturized coaxial preamplifier Ultra Low Noise for radio frequency frequencies from 400 to 406MHz with SAW filter input and bias-tee power circuit.
Perfect for amplifying the weak signals of the radio sensors. You can connect it directly to the TTGO module or directly to the SDR key.
Thanks to the input SAW filter with a bandwidth of only 7 MHz, it is possible to eliminate any frequency outside the 400 and 406 MHz. Excellent for eliminating the problems of desensitization and intermodulation caused by telephone cells, TV and radio broadcasters.
Can be powered via bias tee directly from the TTGO or SDR key (subject to minor modification)./p>
