USEFUL Information and Conversion Tables for RF Engineering

Coupling Factors for Directional couplers:

In general Directional Couplers are provided with the manufacturer's plots across the frequency spectrum for which the Directional coupler is specified. Please left click here Coupling Factor or left click on the buttons below to view conversion tables and access conversion formula.

Convert dBm to Watts:

 Converting transmission Power in dBm to Watts is a very useful tool particularly when computing transmission power (ERP). Please left click here dBm to Watts or left click on the buttons below to view conversion tables & access conversion formula .

Convert VSWR to Return Loss:

 Different manufacturers describe RF devices such as filters and matching units in either VSWR or Return Loss (RL). The conversion table shows the relationship between the VSWR ratio and the equivalent Return Loss in dB.  Please left click here VSWR to R L or left click on the buttons below to view conversion tables and access conversion formula.
