About
The 4-channel C-band Multiplexer is a passive high-frequency device of flight communication equipment that provides filtering of repeated C-band signals from four transfer devices. Channel 1: 3430–3482.5 MHz (center 3456.25 MHz, ≤0.38 dB loss). Channel 2: 3605–3645 MHz (center 3625 MHz, ≤0.42 dB). Channel 3: 3495–3535 MHz (center 3515 MHz, ≤0.42 dB). Channel 4: 3857–3893 MHz (center 3875 MHz, ≤0.45 dB). All channels: reverse losses ≥18 dB, input isolation ≥20 dB. Nominal input power 125 W per channel, maximum output 500 W. Released in 2016 with 15-year guaranteed service life and 4-month delivery time.
