CX2156NL

Balun Overview

The CX2156NL is an RF balun transformer manufactured by Pulse Electronics, designed for wideband applications. It operates within a frequency range of 2.3MHz to 2.7GHz with a 1:1 impedance ratio between balanced and unbalanced ports. The component features a maximum insertion loss of 0.2dB and utilizes a 5-SMD鸥翼 (gull-wing) surface mount package. It complies with RoHS3 standards and holds an MSL rating of 1. This device is intended for signal conversion in RF circuits.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion across a wide frequency spectrum
• Low insertion loss design ensures minimal signal degradation
• Surface mount construction facilitates automated PCB assembly

Balun Applications

• RF/IF circuit signal balancing
• Wideband antenna interface matching
• RFID system components

Balun Procurement Notes

Verify current availability status as the product may be discontinued or subject to end-of-life notices. Confirm that the specific ordering suffix matches the required 5-SMD gull-wing package configuration. Ensure compliance with RoHS3 regulations and check for any recent product change notifications affecting specifications or manufacturing origin before finalizing procurement orders.

Balun Selection Notes

Select this component when a 1:1 impedance transformation is required for frequencies spanning from low MHz to high GHz ranges. The choice is driven by the need for low insertion loss in sensitive RF paths. Consider the physical footprint constraints of the 5-SMD package during layout design. Verify thermal and environmental operating limits against application requirements.
