R&D Microwaves introduced a 1 to 18 GHz high power taperline coaxial coupler featuring a combination of high performance specifications that are excellent for instrumentation test or system applications. Model C1-B12 covers the full frequency range with +/-1 dB accuracy, including frequency flatness, in 20 or 30 dB coupling values. The unique tapered coaxial air dielectric structure has minimal insertion loss of typically 0.2 dB and is capable of handling power levels up to 600 W. Input return loss and directivity is better than 15 dB over the full frequency range, and typically 25 dB over most of the frequency range. The unit inherently has low PIM performance for applications where that is critical.
