Urvashi SengalApplications Engineer, Mini-Circuits Directional couplers are an important type of signal processing device. Their basic function is to sample RF signals at a predetermined degree of coupling, with high isolation between the signal ports and the sampled...

Ultra-Wideband, Low-Loss Couplers for Cable TV and Broadband Access Systems (DOCSIS® 3.1)

by minicircuitsadmin | Mar 21, 2018 | Directional Couplers, Engineering Resources

I. Background This article discusses the use of ultra-low loss, broadband distributed couplers in 75Ω systems such as broadband services over cable television networks (CATV). CATV systems require continuous monitoring of output power in the forward (downstream) path...

Coupler Theoretical Main-Line Loss Calculation (AN-30-004)

by minicircuitsadmin | Oct 28, 2015 | Directional Couplers, Engineering Resources

I. Introduction The main-line loss of a coupler is defined as the loss between the input and output ports. Theoretical loss is defined as that of a perfect (lossless) coupler, for which the input power is the sum of the (main-line) output power and the power at the...
