Description

FM duplex, multiplexer For programs with multiple sets of FM radio stations by multiple transmitters share an antenna, fed by multiple methods for the best. FM multiplexer must meet the following three requirements: 1. The input return loss � *6db 2. Multiplexer of any connection between the two transmitters have enough isolation. 3. Each must have an appropriate input impedance matching. I produced the type and power level multiplexer. Star duplexer: power rating are: **0W, 1KW, 3KW, 5KW, *0KW. Bridge-type diplexer power levels are: **0W, 1KW, 3KW, 5KW, *0KW. Hybrid multiplexer power levels are: **0W, 1KW, 3KW, 5KW, *0KW Multiplexer Specifications: 1. Frequency range: *7 ~ **8MHz 2. Power: **0W, 1KW, 3KW, 5KW, *0KW 3. Input Impedance: *0 Ω / coaxial 4. Output Impedance: *0 Ω / coaxial 5. Input, output interface: customer choice (L*7, �*0, IF*5 and IF*0Ф*0, etc.) 6. Bandwidth: � **0KHz 7. Insertion Loss: � 0.5db (**0W 1KW) � 0.3db (3KW 5KW) 8. Minimum frequency interval Star � 4MHz Bridge � 1.5 MHz 9. Frequency of isolation among � *0db (3KW 5KW) *0. The input return loss � *6db
