DBTC-20-4-75LX+

RF Directional Couplers Overview

The DBTC-20-4-75LX+ is a surface-mount directional coupler from the Mini-Circuits DBTC series, designed for 75 Ohm systems. It operates within a frequency range of 5 MHz to 1.25 GHz and features a nominal coupling coefficient of 20 dB. The component utilizes a micro-miniature SMD package with dimensions of 0.150 x 0.150 inches and a height of 0.150 inches. It exhibits a maximum insertion loss of 1.5 dB and supports board mount installation.

RF Directional Couplers Feature Summary

• Provides precise signal sampling via 20 dB coupling in 75 Ohm environments
• Supports wideband operation from 5 MHz to 1.25 GHz
• Utilizes compact micro-miniature surface mount footprint

RF Directional Couplers Applications

• CATV network signal monitoring
• Broadband access system integration
• RF test and measurement setups

RF Directional Couplers Procurement Notes

Verify the specific suffix '75LX+' against the official datasheet to confirm the 75 Ohm impedance and low-profile variant characteristics. Ensure compatibility with existing 75 Ohm PCB traces and assembly processes. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement orders.

RF Directional Couplers Selection Notes

Select this model for applications requiring directional coupling in 75 Ohm infrastructure rather than standard 50 Ohm systems. Consider the 1.5 dB maximum insertion loss when calculating total link budget. Evaluate the physical dimensions against available board space constraints due to the micro-miniature case style.

RF Directional Couplers Part Context

This component belongs to the DBTC family of directional couplers manufactured by Mini-Circuits. These devices are engineered for passive RF signal conditioning. The product line includes various coupling values and impedance options to support diverse RF circuit architectures.

RF Directional Couplers Replacement Considerations

Cross-reference part numbers such as DBTC-20-4+ or DBTC-6-4-75LX+ only if system impedance requirements change or different coupling ratios are needed. Verify that any substitute maintains the required 75 Ohm characteristic impedance.
