RF directional couplers are readily available with common interfaces such as N type female connectors. Aviel Electronics, a division of RF Industries (NASDAQ: RFIL), announced that it now designs and manufactures RF directional couplers with uncommon interfaces such as the HN female shown in the above photo. The HN coaxial interface is a high-voltage version of the N interface and is used in specialized applications. Other interfaces are available.
Model number Z-344, shown in the picture, operates in a frequency range of 700 to 850 MHz with power handling capability of 40KW peak power (120W average power). Insertion loss is less than 0.2dB and VSWR is less than 1.1 for both the main and secondary lines. Forward coupling is 43 dB isolation. Reverse coupling is 33 dB isolation.
