The DPF 1400/6 from Amphenol Procom are 6-Cavity Duplex Filters with a passband from 1240 to 1600 MHz. They are designed for duplex radio transceiver systems where the Tx and Rx operate on different channels. These filters can handle an input power of up to 50 W and have an insertion loss of less than 1.0 dB. They provide adjustable Tx-Rx spacing of 35 MHz with an option for 28 MHz and provide an isolation of more than 85 dB from the adjacent band.
These duplex filters use full-length ¼ ? cavities and are made of passivated steel with Teflon insulation for coaxial cables and connectors with black vinyl-coating to prevent corrosion. They are available in modules that measure 135 x 154 x 33 mm with N-type (female) connectors and includes an option for BNC, TNC, UHF, and SMA connectors.
