Abstract
The directional coupler supports ultra high bandwidth of 5600 MHz (from 400 MHz to 6 GHz) in compact structure and also provides high directivity of (>15 dB). The coupler uses a two stage micro-strip directional coupler for a frequency range of 400 MHz to 6 GHz, where the first stage supports a frequency of operation from 0.4 GHz to 1 GHz and the second stage supports a frequency of operation from 1 GHz to 6 GHz and the required coupled port can be chosen using a radio frequency switch as required by the application used in.
