The RFS LPF low pass filter provides a minimum of 40dB rejection up to 3.3 GHz. A custom designed structure is used to create a very sharp cut-off rate and to maintain high rejection. Unlike traditional coaxial low pass filters, the RFS LPF does not exhibit the typical rejection band periodicity. High quality insulating material is used throughout the internal design of the low pass filter leading to high power handling capability and very low insertion loss while keeping dimensions small. With the lowpass filter installed a broadcast TV transmitter can be safely operated in co-location with other wireless services such as GSM1800 and WiFi.
