PDF On Jul 1 2016 R Vishnu published Design and development of a dual directional coupler with transformers for HF band applications
The circuit provides a high degree of accuracy in the relationship of the forward and reflected samples over a wide range of load impedances It also has
A directional coupler separates signals based on the direction of signal propagation These devices are used to unequally split the signal flowing in the
A directional coupler is used to sample the RF energy travelling in a transmission line useful for measuring power frequency and VSWR or impedance
The best theoretical performance available from a directional coupler using ideal transformers is a function of the turns ratio and the terminating
A broadband directional coupler based on ferrite cores is proposed for high frequency HF Very high frequency VHF Ultra High Frequency And finally the coupler itself must have good directivity the ability to distinguish between forward and reflected power This one exceeds 30db across it s
Directional couplers are HF components where a dedicated part of the main signal signal is different depending on the design oft he directional coupler
