Filter 420-450MHz, 4.5MHz Pass Bandwidth


RFI’s range of compact multi-resonator milled aluminium band pass filters are ideal for use where space is restricted or at a premium and where a 19” rack mounting facility is available. The symmetrically sharp skirt response and low pass band insertion loss make these filters ideal for use as pre-selectors in receiver systems or as post filters cleaning up transmitter carriers (power rating dependent) or Tx sub-bands. DC grounding in the input/output ports provide natual voltage surge protection. The temperature stable resonators provide a wide operational temperature range ensuring important electrical specifications are maintained in extreme temperature conditions.
