New SGQ-450D 400-470Mhz UHF 6 Cavity Duplexer 50W FREE tune radio repeater

modname=ckeditor SGQ-450D UHF 6 Cavity Duplexer  50W N Connector FREE tune radio repeater Duplexer The standard frequency difference is 10MHz. The frequency range of the frequency difference is 5MHz-20MHz (non-standard), and the frequency difference within this range can be produced. Customers are required to provide frequency customization. At the same time, the actual parameters of the duplexer will change with the change of the duplexer’s frequency difference. Note: 1. When the frequency difference becomes smaller, the insertion loss will become larger and the isolation will become smaller. When the frequency difference becomes larger, the insertion loss will become smaller and the isolation will become larger (the better the performance) 2. The customer customizes the frequency and after receiving the goods, (key point, many customer complaints are due to this reason) If customers need to debug by themselves, the frequency difference of the duplexer cannot be changed (emphasis), and the frequency can only be shifted by ± 3~5MHz 1. Prepare the tools: * three-port network analyzer * 30W dummy load with N male connector * 2 x RF cable from duplexer to the network analyzer (From N Female to N/M/BNC connector base on your network analyzer connector type ) * slotted screwdriver * spanner 2. Connect the cables *If want to adjust the low frequency, connect the low port with 30W dummy load, and connect the other two ports on duplexer to the network analyzer. *If want to adjust the high frequency, connect the high port with 30W dummy load, and connect the other two ports on duplexer to the network analyzer. 3. Tune the frequency Power on your network analyzer, according the guidance on frequency network, using it to monitor the frequency, adjust the six screw poles on duplexer with slotted screwdriver to the frequency you want. 4. Fasten the screws Use spanner to fasten the screws on above step.
