DBTC-16-5-75X+

RF Directional Couplers Overview

The DBTC-16-5-75X+ is a surface-mount directional coupler designed for 75-ohm systems, operating from 5 MHz to 1.5 GHz. It features a nominal coupling of 16.8 dB with a tolerance of ±0.7 dB and handles up to 1 Watt of power. The component utilizes a TopHAT® SMD package, providing a compact form factor suitable for high-density PCB layouts. It offers stable coupling variation between ±0.5 and 0.7 dB across the frequency range, ensuring consistent signal sampling performance in broadband applications.

RF Directional Couplers Feature Summary

• Surface-mount TopHAT® package design for automated assembly and space efficiency
• Optimized for 75-ohm impedance systems typical in CATV and broadband networks
• Broadband operation covering 5 MHz to 1.5 GHz frequency range

RF Directional Couplers Applications

• CATV distribution networks
• Broadband access infrastructure
• DOCSIS system signal monitoring

RF Directional Couplers Procurement Notes

Verify the ordering suffix 'X+' confirms RoHS compliance and lead-free termination specifications as per Mini-Circuits standards. Ensure the 75-ohm impedance requirement matches your system architecture, as this component is not compatible with standard 50-ohm designs without matching networks. Confirm that the 1-watt power handling capacity meets the maximum expected signal levels in your specific application path to prevent device degradation.

RF Directional Couplers Selection Notes

Select this model when integrating passive signal sampling into 75-ohm cable television or broadband architectures requiring minimal insertion loss impact. The fixed 16.8 dB coupling value dictates the sample strength; ensure this attenuation level aligns with downstream receiver sensitivity requirements. Consider the physical dimensions of the TopHAT® package during PCB layout planning to maintain adequate clearance for soldering and thermal management within dense circuit board environments.

RF Directional Couplers Part Context

This component belongs to Mini-Circuits' portfolio of passive RF/microwave devices tailored for the cable industry. It complements other 75-ohm components such as transformers, diplexers, and splitters used in DOCSIS 3.1 and 4.0 architectures. The product line emphasizes in-house manufacturing quality and supply-chain stability, supporting both active MMIC designs and passive network elements for comprehensive system optimization.
