X4B20L1-5050G

Overview

The X4B20L1-5050G is an RF balun transformer manufactured by TTM Technologies, Inc. It operates within a frequency range of 1.2 GHz to 2.7 GHz. The device provides a 1:1 impedance transformation between unbalanced and balanced ports, both rated at 50 Ohms. It is housed in a compact 0603 (1608 Metric) surface-mount package with six PCB pads. Key electrical specifications include a maximum insertion loss of 1.0 dB, a minimum return loss of 17 dB, and a phase imbalance of ±1 degree.

Feature Summary

• Provides balanced-to-unbalanced signal conversion for RF applications
• Supports high-density surface-mount assembly via 0603 footprint
• Ensures signal integrity through low insertion loss and tight phase balance

Applications

• Wireless communication systems requiring RF signal conditioning
• Mobile device antenna interface circuits
• RF front-end modules in telecommunications infrastructure
