X4BD40L1-50100G

Overview

The X4BD40L1-50100G is an ultra-small, low-profile RF balun transformer manufactured by TTM Technologies. It operates within a frequency range of 2.3GHz to 6GHz and provides a 1:2 impedance transformation ratio between 50 ohms unbalanced and 100 ohms balanced ports. The component features a maximum insertion loss of 1.2dB and a minimum return loss of 10.5dB. It utilizes a 0603 (1608 Metric) surface mount package with six PCB pads.

Feature Summary

• Ultra-small form factor designed for space-constrained differential input and output applications
• Low-profile construction optimized for modern high-frequency circuit board layouts
• Balanced to unbalanced signal conversion capability for RF signal integrity

Applications

• 5G wireless infrastructure systems
• Differential RF input/output circuits
• High-frequency communication modules

Procurement Notes

Verify the specific datasheet version from TTM Technologies prior to ordering, as specifications may vary between revisions. Confirm that the 0603 footprint matches the target PCB design exactly. Ensure supply chain sources are authorized distributors to guarantee component authenticity and traceability. Check RoHS compliance status if required by project regulations.

Selection Notes
