HI,What would be the ideal value of VSWR for a BTS? sagitraz 02-February-2009 07:31:36 PMComments In general vswr is normally 1 but 1.3 and 1.7 is use in Telenor useing NSN. Posted by HamidAliKhan If you go by theory Source Impedance should be equal to Load impedance, then maximum power gest transferred from source to load. but ideally this is not the case so some power will be reflected back to source. Which will result in standing waves in transmission line. So VSWR should be ideally 1. Posted by waqqas1 VSWR is a voltage standing wave ratio. it indicates the mismatch between load impedance and source impedance. If you go by theory Source Impedance should be equal to Load impedance, then maximum power gest transferred from source to load. but ideally this is not the case so some power will be reflected back to source. Which will result in standing waves in transmission line. So VSWR should be ideally 1. What is allowed may vary from operator to opeartor. So ideal value should be near to 1. We allow 1.17 Posted by jmehta vswr is normally 1 but 1.3 and 1.7 is use in Telenor useing NSN. Posted by crouse VSWR(Voltage standing wave ratio) & for general ideal value would be 1 but for huawei bts it would be 1.4. Posted by Hash007 |
