Directional Coupler Octave Model-NF (C-NF Series)
MCLI’s expertise in passive components also extend to directional and bi-directional couplers offered in broadband frequency ranges feature low insertion loss, high directivity, and low VSWR. All directional couplers have, at a minimum, an input, output, and coupling port. Signal power reflection is prevented because the coupling ports signals are isolated from the line output port. Directional couplers are used to isolate, separate, and combine signals in measurement applications. MCLI couplers are offered in both directional and dual directional with many low frequency and high power solutions utilizing both stripline and lumped element technology.
