ADC-17-122-75+ is a 75Ω surface-mount directional coupler designed for applications requiring 17 dB coupling over a 5 to 1250 MHz bandwidth, including DOCSIS 3.1 systems. It features a mainline loss of 0.8 dB typ. up to 1000 MHz and 1.0 dB typ. from 1000 to 1250 MHz, coupling flatness of ±0.4 dB typ. up to 1000 MHz, and input power handling up to 1 W. The device is housed in a 6-lead plastic package measuring 0.27 × 0.31 × 0.11 inches, with typ. VSWR of 1.15:1 and isolation of 25 dB typ. from 870 to 1250 MHz. It is RoHS compliant and operates from −40°C to 85°C.
Mini-Circuits’ ADC-17-122-75+ is a 75Ω surface-mount directional coupler providing 17 dB coupling from 5 to 1250 MHz, supporting bandwidth requirements for DOCSIS 3.1 systems and equipment. This model, provides excellent coupling flatness, low mainline loss, good VSWR and RF input power handling up to 1W. The unit comes housed in a miniature 6-lead plastic package (0.27 x 0.31 x 0.11”), saving space in dense PCB layouts.
