Low Pass/Harmonic Filters are primarily used to control unwanted components of a signal. Characteristically low loss and small in size, these lumped constant filters are used to attenuate harmonics in the transmitting path or to attenuate high levels of out-of-band interfering signals in a receiver path. RFI have a number of banded low pass/harmonic filter models suitable to use on fundamental carrier frequencies from 132MHz to 960MHz.

RFI DC Injectors/Pickoffs enable the coupling of DC 'onto' an RF coaxial cable and the de-coupling of DC 'off' an RF coaxial cable. The DC voltage range can be negatively or positively earthed between 12 to 48 Volts. For DC injectors/pickoffs requiring additional lightning protection please refer to the lightning protection product range.

3-Port directional couplers, although primarily used in distributed antenna systems, are useful in a number of RF system applications. RFI have a wide frequency range and coupling values to choose from.

RFI RF Samplers provide a decoupled RF port via an in-line low loss coupler unit. Fixed decoupled values across a predetermined frequency range provide a useful facility to monitor power levels or the integrity of sampled RF power without necessarily increasing the overall system insertion loss. 3-pot and 4-port directional couplers can also be used as RF samplers. The 3-port coupler will effectively sample only decoupled forward power through the unit, whereas the 4-port directional coupler is able to measure either forward or reverse decoupled power depending on the coupling port selected.

The RFI RF-over-Fibre (RFoF) modem product range provides a number of broadband frequency and configuration options.
