R&K Directional Couplers (DC Series)
R&K’s DC series products are directional couplers that employ either high-frequency ferrite transformer or microstrip-line structured method. Directional couplers are for detecting the high-frequency signal level passing through between input port and output port.
The directivity in a coupler is the ratio between the input signal at the coupled port and the unwanted reflected signal at the coupled port. It is a measure of how well the coupler isolates two opposite-traveling (forward and reverse) signals at the coupled port.
Our standard DC series products offer the selection of operating frequency from 500 kHz to 4500 MHz with coupling from 14.5 to 30dB.
