430-436 MHz Filtered LNA | 70cm & 433 MHz ISM Amplifier Notch Filter Frequency Typical Insertion LossPRODUCT OVERVIEW The GPIO Labs 433 MHz Filtered Low Noise Amplifier boosts weak signals in the 430436 MHz range while rejecting strong out of band interference cellular, LTE, UHF, 915 MHz and 2. 4 GHz ISM traffic that can swamp a receiver's front end in this crowded spectrum. The design delivers 20 dB of gain across the 430436 MHz passband with <1 dB noise figure, giving weak signal 433 MHz and 70cm systems the sensitivity boost needed to pull signal
