The RDC-16-182-75+ is a surface-mount directional coupler designed for 75Ω broadband applications from 5 to 1800 MHz, supporting DOCSIS 3.1 and cable TV systems. It features a nominal 16 dB coupling with ±0.3 dB flatness, mainline loss of 1.1 dB typical at 1218 MHz, and return loss of 18 dB typical at the coupled port. The device handles up to 2 W input power and operates from -40°C to +85°C. It is housed in a TT2315-3 case measuring 6.35 × 7.11 × 4.19 mm with wrap-around terminations for improved solderability and inspection. External 75Ω termination is required at pin 4. The part is suitable for systems requiring low heat dissipation and high isolation up to 45.86 dB at 1200 MHz.
Mini-Circuits’ RDC-16-182-75+ surface-mount directional coupler provides 16 dB coupling with excellent flatness, low mainline loss, and good return loss for 75Ω applications from 5 to 1800 MHz, supporting a variety of broadband applications including DOCSIS 3.1 systems and equipment. This model features core and wire construction with wrap-around terminations for good solderability and easy visual inspection.
