ULTRA-FLAT DIRECTIONAL COUPLERS
This series of ultra-flat broadwall couplers is designed for precision
measurements in microwave circuits when the ultimate in flatness of coupled
output power is required. A unique design concept of combining tow
Tchebycheff coupling arrays is incorporated to achieve this uniform
output. The coupling sensitivity is plus or minus 0.2 dB maximum over the
full waveguide operating range.
Standard values of couples are offered. Other
special coupling values are available on special request. Alternate
materials and flanges are available. See flange section. For power
ratings of built-in terminations, refer to ratings on Page 33 (-54
series). Finish is instrument gray enamel.
