The Teroz 428X antenna amplifier with filters above and below the K23 to K48 operating band filters out a lot of interfering frequencies caused by mobile phones in the 5G LTE (690 to 862 MHz) + GSM (850 to 960MHz) + CDMA (455/465MHz) + UFON (410/420 MHz) + Track-side signaling (approx. 469 MHz).
The Teroz 428X antenna amplifier with filters above and below the K23 to K59 bandwidth filters out a lot of interfering frequencies caused by mobile phones in the LTE + GSM + UFON + CDMA bands. It is a selective amplifier with low-noise high-frequency transistors BFP, BFR. The input is a selective combination of high and low pass filters. The amplifier noise will be increased by the low pass filter attenuation, while increasing the immunity to UFON, CDMA, 5G, LTE and GSM signal interference.
